Abstract (sommario):

AbstractTo support the concurrent design processes of mechatronic subsystems, unified mechatronics modeling and cooperative body–brain coevolutionary synthesis are developed. In this paper, both body-passive physical systems and brain-active control systems can be represented using the bond graph paradigm. Bond graphs are combined with genetic programming to evolve low-level building blocks into systems with high-level functionalities including both topological configurations and parameter settings. Design spaces of coadapted mechatronic subsystems are automatically explored in parallel for overall design optimality. A quarter-car suspension system case study is provided. Compared with conventional design methods, semiactive suspension designs with more creativity and flexibility are achieved through this approach.

Abstract (sommario):

This paper explains the concept of mechatronics and tries to resolve problem of leadership. It consists of four overlapping circles: mechanical systems, electronic systems, control systems, and computers. Their overlaps form digital control systems, control electronics, electromechanics, and mechanical computer-aided design. The question of who owns mechatronics—who will lead the development of next-generation electromechanical systems—often depends on where engineers work. Companies that make mechanical systems tend to let mechanical engineers lead; those that make electronics assign the lead to software and electrical engineers. In the future, though, the issue may be decided by how colleges train the next generation of mechanical engineers. Right now, most schools teach controls, basic electronics, and programming as part of the mechanical engineering curriculum. Universities are introducing courses with a goal to integrate courses so that electrical, control, and mechanical engineers learn how different disciplines use the same core knowledge to achieve different results.

Abstract (sommario):

We have developed educational materials on mechatronics with microcomputers embedded as a core as often found in autonomous robots. The developed educational materials are expected to obviate needs for other educational materials to learn a wide range of mechatronics from autonomous robots to factory automation systems as well as learn step by step from visually comprehensible tiling programming to C-language programming. We have used the developed educational materials at the workshops we have conducted as a part of the three-year humanresource development project for small and medium enterprises. In addition, we have compiled into textbooks know-how we have acquired at the workshops and have applied it to the experimental practices of the College.

Abstract (sommario):

In the paper an application of vision methods and algorithms in various domains that contribute to mechatronics is presented. Regarding mechatronics devices and machines as robots, a vision system employed for a testing station simulating an industrial assembly line is discussed. Some numerical aspects concerning image pre-processing, analysis and geometrical transformations commonly used in robotics were introduced. To accomplish an effective investigation, the developed methodology and algorithms were implemented and verified on an experimental setup composed of two industrial robots and automation devices cooperating with two various vision systems. In the case of underwater robots for tank inspection, image pre-processing and analysis algorithms for the robot's position estimation, an image scale calculation and wall crack detection were investigated. An active vibration control system is treated as a mechatronic device which contains mechanical parts, electronics and software. In this example, a visual servoing architecture based on image features for controlling an active vibration control system was examined. For an effective investigation and synthesis of visual servoing algorithms, a MATLAB/Simulink/dSPACE hardware–software environment was employed. A vision system was used to analyze vibration amplitude of the vibro-isolation mass of the active suspension system and to provide a feedback control signal. The connection of 3D vision techniques with modal analysis was shown. Within the confines of the project a methodology for amplitude of vibration measurement and a software tool for modal analysis realization based on visual data were developed. The 3D measurements and structure of the construction were obtained by application and development of passive 3-D vision techniques. From this area, ‘structure from motion’ techniques were developed. In the experimental research, a mechatronic test stand was designed and manufactured enabling automatic two-axis control of a camera. A frame structure was built, in which a guiding-rail system was mounted enabling straight-line motion of a camera. Additionally, a system realizing rotational motion of a camera was built in. To control the experiment stand, software was created enabling the combination of the hardware-software part of the stand with the software part of a vision system. A tool was developed for the purpose of modal analysis and estimation of the quantities characterizing dynamic properties of the structure based on vision signals. As a conclusion, the presented, implemented and tested vision methods in various hardware-software programming platforms are discussed

Abstract (sommario):

The marriage of computer, electronic technology and traditional machining disciplines has given birth to revolutionary new disciplines, Mechatronics. Therefore Mechatronics requires mechanical, electronic and computer knowledge together. The main aim of this article is to present the mechatronics approach for desk-top CNC milling machine design. Construction of computer controlled (CNC) Machine differs greatly from that of conventional machine tools. This difference arises from the requirement of higher performance levels. Machine Structure, guide ways, feed drives, spindle and spindle bearings, measuring systems, machine control unit, software and operator interface, gauging and tool monitoring should be considered as mechatronics approach. Servo motors, motor drivers and motor control unit were used in this CNC milling machine to make it flexible and easy programming. Ball screws were used to X-Y –Z axes to eliminate backlash of the slides. Non-contact home and Limit switches were used to prevent possible damages against over travels. Necessary torque and power have been calculated to select the motors by taking care of the load, ball screws, motor inertia and required cutting tools and etc. and developed CNC milling machine has been tested several times for reliable machining of machine parts.

Abstract (sommario):

In recent decades, a Model-Based Predictive Control (MPC) has revealed its dominance over other control methods such as having an ability of constraints handling and input optimization in terms of the value function. However, the complexity of the realization of the MPC algorithm on real mechatronic systems remains one of the major challenges. Traditional predictive control approaches are based on zero regulation or a step change. Nevertheless, more complicated systems still exist that need to track setpoint trajectories. Currently, there is an active development of robotics and the creation of transport networks of movement without human participation. Therefore, the issue of programming the given trajectories of vehicles is relevant. In this article, authors reveal the alternative solution for tracking non-standard trajectories in spheres such as robotics, IT in mechatronics, etc., that could be used in self-driving cars, drones, rockets, robot arms and any other automized systems in factories. The ability of Model-Based Predictive Control (MPC) such as the constraints handling and optimization of input in terms of the value function makes it extremely attractive in the industry. Nevertheless, the complexity of implementation of MPC algorithm on real mechatronic systems remains one of the main challenges. Secondly, common predictive control algorithms are based on the regulation approach or a simple step shift. However, there exist systems that are more complicated where a setpoint to be tracked is given in the form of trajectories. In this project, there were made several modifications in order to improve an MPC algorithm to make better use of information about the trajectories.

Abstract (sommario):

The researchers conducted a study in a ‘Computer Programming’ course of three engineering departments (Civil, Industrial and Mechatronics) in a Turkish private university (n=240). A closed Facebook group was set up for serving as an LMS for the course. At the end of the semester, the students were given a survey of three sections; demographic questions, three opinion based questions on Facebook group use and thirty two Facebook in education perception related 5-Likert scale. The mean scores showed that majority of the students liked using a closed Facebook group. The two most important reasons were accessing the shared lecture notes ubiquitously and keeping themselves updated on anything related to the course. Additionally, the students agreed the idea of keeping Facebook group as secret and the importance of establishing group rules. The students also reported that the Facebook group was not a waste of time or uninteresting for them. Lastly, comparison tests showed that there were certain items yielding significant differences based on gender, school year and department variables.

Abstract (sommario):

The field of cyber-physical systems is a growing IT research area that addresses the deep integration of computing, communication and process control, possibly with humans in the loop. The goal of such area is to define modelling, controlling and programming methodologies for designing and managing complex mechatronics systems, also called industrial agents. Our research topic mainly focuses on the area of data mining and analysis by means of multi-agent orchestration of intelligent sensor nodes using internet protocols, providing also web-based HMI visualizations for data interpretability and analysis. Thanks to the rapid spreading of IoT systems, supported by modern and efficient telecommunication infrastructures and new decentralized control paradigms, the field of service-oriented programming finds new application in wireless sensor networks and microservices paradigm: we adopted such paradigm in the implementation of two different industrial use cases. Indeed, we expect a concrete and deep use of such technologies with 5G spreading. In the article, we describe the common software architectural pattern in IoT applications we used for the distributed smart sensors, providing also design and implementation details. In the use case section, the prototypes developed as proof of concept and the KPIs used for the system validation are described to provide a concrete solution overview.

Abstract (sommario):

The aim of this study was to develop methods for building intelligent systems that ensure safe movement on a planned and specified trajectory in an environment with unknown obstacles for planning the movement of a mobile robot. To achieve this goal, modern concepts and methods of planning systems development were analyzed. By moving a mobile robot in an unknown environment, it is proposed to develop an intelligent system for planning its modeling in an uncertain static environment, to realize an intelligent system for planning the movement of a mobile robot in an unknown dynamic environment and modeling the resulting system. As a result, analytical studies were conducted on a computer using mathematical modeling, analytical geometry, kinematic and dynamic analysis, fuzzy logic, neural networks, robotics, mechatronics, discrete integration and applied programming methods, and experimental studies were conducted using a mobile robot model.

Abstract (sommario):

This paper presents a proposal of a complex mechatronic system that enhances the effectivity of obtaining energy from renewable resources. The main focus is on the photovoltaic energy system, which obtains electricity from the conversion of solar radiation through photovoltaic crystalline silicon-based panels. The design of the complex mechatronic system consists of several steps. The structural design of the photovoltaic panel positioning unit in the form of a three-dimensional model is made in the selected modelling programming environment. Subsequently, a propulsion system is proposed for the designed structure, the functionality of which is verified in the programming environment Automated Dynamic Analysis of Mechanical Systems. The control system design using a programmable logical controller is also presented. The corresponding control algorithm is designed in the programming environment Step7 and covers the optimal positioning of photovoltaic panels. The developed application in the WinCC environment provides a visualization of the positioning control process. The conclusion is devoted to the assessment of the obtained results for the proposed complex mechatronic system for photovoltaic panel positioning in comparison with photovoltaic panels in fixed installation. The presented results were obtained by simulations.

Abstract (sommario):

Modern CNC machine tools constitute advanced mechatronic systems. Numerous works are undertaken on the development of new intelligent control systems for CNC machine tools [1–5] equipped with unique diagnostic systems. One of the development directions of CNC control systems is exploring new forms and techniques of operator-machine communication as well as new, simpler machine tool programming procedures. Nowadays, there are many techniques for programming CNC machine tools [6], [7]. These techniques have taken a variety of forms both due to historical limits of technology and various environmental requirements. Despite the existence of complex control systems for operation and programming CNC machine tools or CAD/CAM systems facilitating the generation of a machining strategy for complicated elements, there is a demand for machine tools that are easier to operate, and therefore do not require advanced programming skills for operation.

Abstract (sommario):

A biped walking robot, named EP-WAR3 (Electro-Pneumatic-Walking-Robot), has been designed, built and tested at LARM (Laboratory of Robotics and Mechatronics) in Cassino. EP-WAR3 is provided with a suitable binary pneumatic actuation in order to be controlled through a common PLC (Programmable-Logic-Controller) as an event-based system in an on/off environment. The walking stability of the biped robot is obtained by using suction-cups, which are installed on the underside of each foot. EP-WAR3 is able to walk along a straight line with two different step sizes, turn right and left, and to climb and to descend stairs. A suitable motion analysis and programming technique of the PLC controller is proposed in order to obtain suitable walking capabilities and flexibility of the robot.

Abstract (sommario):

Virtual remote laboratories have already been successfully implemented in educational centers for practical learning of mechatronics and robotic systems. This article presents the development of a virtual articulated UR-type robot, designed as an educational tool that is suitable for programming and evaluating both the inverse kinematics control of the robot and the independent control of the robot joints. The 3D model of the virtual robot was developed in the Blender V2.79 software and uses the Modbus TCP industrial communication protocol for the communication to an external controller implemented in CoDeSys V3.5 software. The developed system allows the students to generate and test their own control algorithm for the robot joints with the visualization of the achieved performance in 3D and real time. Tailored control systems can be compared on the virtual robot. In this study, a novel technique for the joint position control based on an FSM is proposed and verified with the virtual UR5 robots to prove that the developed system is a suitable platform to teach and learn the inverse kinematics control and independent joint control of the UR5 robotic arm.

Abstract (sommario):

The paper examines the ease of use of a mechatronic system by children aged 7-12+ years living in the area of Thessaloniki. The research was conducted on students who participated in educational robotics seminars and as the results show, the trainees consider a mechatronic system very easy to use. The study concluded that older boys in particular were more familiar, than girls, in the construction and the programming of mechatronic systems. Children seem to be excited and this is evidenced by their strong desire to use it often. The area criterion does not make difference to the results. It seems clear that a mechatronic system is easy to use by primary school children. Through educational robotics, children can be taught in the different objects that combine this special tool. Learning takes the form of a game and escape from the narrow boundaries of conventional teaching that is now outdated and without interest.

Abstract (sommario):

Mechatronics and robotics appeared particularly effective in students’ education, allowing them to create non-traditional solutions in STEM disciplines, which have a direct impact and interaction with the world surrounding them. This paper presents the current state of the MiniCERNBot Educational Robotic platform for high-school and university students. The robot provides a comprehensive educative system with tutorials and tasks tuned for different ages on 3D design, mechanical assembly, control, programming, planning, and operation. The system is inspired to existing robotic systems and typical robotic interventions performed at CERN, and includes an education mock-up that follows the example of a previous real operation performed in CERN’s Antimatter Factory. The paper describes the learning paths where the MiniCERNBot platform can be used by students, at different ages and disciplines. In addition, it describes the software and hardware architecture, presenting results on modularity and network performance during education exercises. In summary, the objective of the study is improving the way STEM educational and dissemination activities at CERN Robotics Lab are performed, as well as their possible synergies with other education institutions, such as High-Schools and Universities, improving the learning collaborative process and inspiring students interested in technical studies. To this end, a new educational robotic platform has been designed, inspired on real scientific operations, which allows the students practice multidisciplinary STEM skills in a collaborative problem-solving way, while increasing their motivation and comprehension of the research activities.

Abstract (sommario):

The modeling and control of complex, non-linear, and time-changing mechatronic systems requires complex software development. They are carried out in the prototyping phase with engineering software development tools, generating models, and control algorithms that are not always easily exportable to control hardware. The following work offers an alternative that considers Model-Based Design using graphics-based languages, which facilitates programming tasks for modeling and controlling mechatronic devices and their transition from prototype to control hardware. Model-Based Design with high abstraction programming level capabilities provides the user with a fast coding and testing environment, suitable for laboratory prototyping and subsequent transfer to commercial embedded controllers. The proposed solution combines control hardware based on an STM32H7 microcontroller and a software development environment using graphics-based languages developed for MATLAB. The result is a solution that integrates control hardware and software in a hardware-in-the-loop paradigm. This solution provides robust and energy-saving controllers and demonstrates that an advanced control algorithm can be set up in a critical safety-compliant low-cost embedded controller via a custom model-based design. Algorithms and tools are transferred to the controller without losing the advantages gained in the prototyping phase. Finally, experimental results implementing an adaptive controller in a DC motor and in a pneumatic system are shown to validate the system.

Abstract (sommario):

Robotics of medical recovery represent a subject of great interest among various research centers that are trying to develop different complex systems dedicated to the recovery of motor functions through fulfilling the required tasks imposed by applied therapy programs. In order to implement the concept of 'robotical therapy' it is required to use a robotic system specially designed to adhere to medical protocols and to meet the requirements of therapeutic exercises by programming the command and control unit. This paper is in the field of mechatronic systems used in medicine because the purpose of this kind of equipment is to help patients who underwent surgery in the lower limbs regain the mobility of the affected joints as soon as possible. The proposed objective is to improve an exising concept so that a patient may be able to use it in the comfort of their own house, but still being 24/7 monitorized using various sensors and even being able to contact medical care assistance in case of emergency.

Abstract (sommario):

The brain-computer interface (BCI) is a multidisciplinary research field aimed at helping people with neuromotor disabilities. A BCI system enables the control of mechatronic devices by using cognitive intentions translated into electroencephalographic signals. This paper presents the implementation of LabVIEW-based display systems that can be controlled by a brain-computer interface based on detecting the voluntary eye blinks used as commands. The interactive virtual or physical display systems are helpful thanks to running or simulating various graphical animations or transmitting different text messages in a user-customizable way. The proposed LabVIEW-based virtual display systems provide versatile functionalities such as: customizing the own visual animations and the movement of any text message by switching the direction (to the left or to the right) depending on the user’s choice. This paper presents five original virtual LEDs based display systems developed in LabVIEW graphical programming environment. The implemented LabVIEW applications included: an 8x8 LEDs matrix for simulating graphical animations, 2x16 LCD TEXT for showing text messages, and a 7-segments display for implementing chronometer functionality. Moreover, the LabVIEW virtual display systems were interfaced with the physical display systems (8x8 LEDs matrix controlled by MAX7219 driver and 2x16 LCD TEXT) connected to the Arduino Uno board.

Abstract (sommario):

Heterogeneous test processes with respect to test script languages are an integral part of the development process of mechatronic systems that are carried out in supply chains. Up to now, test cases are not exchangeable between test processes because interoperability is not given. The developed approach enables the source-to-source compiling of test cases between test script languages. With this, the interoperability of test cases is achieved, and seamless integration within the supply chain is possible. The developed approach uses transcompilers as a baseline. In doing so, an interoperability model for test cases is presented. Based on the interoperability model, a source-to-source compiling for test cases is shown. The outcome is a prototype that handles test script languages, which are different with respect to type safety and applied programming paradigms. The approach ensures that test cases are still understandable and usable for test reports. The evaluation confirms the translation capabilities as well as the readability of the generated test case for the high-lift scenario from aviation. The interoperability of test cases within the supply chain enables the formalisation of procedural test knowledge to be used in a broad range of future scenarios, such as test automation, digital twins and predictive maintenance.

In order to implement it on this fast, underactuated mechatronic system, we employ the Gauss–Newton real-time iteration scheme tailored to obtain the efficient solution of the underlying nonlinear optimization problems via sequential quadratic programming. The control performance is experimentally assessed on a real-world laboratory setup featuring an execution timing analysis and hints how to further improve the computational efficiency of the proposed nonlinear estimation control scheme. Even nowadays, the number of practical NMPC applications in the millisecond range is still rather limited, and the presented NMHE-based NMPC of the Pendubot thus also represents a unique case study for control practitioners.

Abstract (sommario):

The paper presents description of a mechatronic control system for mechanical transmission of a 20-ton truck, as well as its adaptive start-up algorithm, transient process behavior which significantly affects durability of automated power unit elements, vehicle movement smoothness and driver’s comfort when driving. A multidisciplinary model of the mechatronic control system has been developed in the software package Imagine Lab AMESim because its power unit including a diesel engine, a dry frictional two-disc clutch, a main mechanical stepped gearbox and an additional gearbox has electrical components besides mechanical and pneumatic ones. The given model allows to test complex control algorithms and analyze the behavior of intelligent systems in the early designing stages. The research has been carried out on the basis of the test complex at Department “Automobiles”, Automotive and Tractor Faculty, Belarusian National Technical University. Research results confirm an adequacy of the AMESim developed multidisciplinary model. Feedback on the increment of an angular velocity difference between driving and driven parts of the friction clutch has been introduced for precise friction clutch control. Threshold values of a feedback parameter have been determined on the basis of the developed computer model and these values will be used for programming a microprocessor unit when implementing an adaptive algorithm for a truck start-up process

Abstract (sommario):

Modern industrial robotic systems are highly interconnected. They operate in a distributed environment and communicate with sensors, computer vision systems, mechatronic devices, and computational components. On the fundamental level, communication and coordination between all parties in such distributed system are characterized by discrete event behavior. The latter is largely attributed to the specifics of communication over the network, which, in terms, facilitates asynchronous programming and explicit event handling. In addition, on the conceptual level, events are an important building block for realizing reactivity and coordination. Event-driven architecture has manifested its effectiveness for building loosely-coupled systems based on publish-subscribe middleware, either general-purpose or robotic-oriented. Despite all the advances in middleware, industrial robots remain difficult to program in context of distributed systems, to a large extent due to the limitation of the native robot platforms. This paper proposes an architecture for flexible event-based control of industrial robots based on the Adept V+ platform. The architecture is based on the robot controller providing a TCP/IP server and a collection of robot skills, and a high-level control module deployed to a dedicated computing device. The control module possesses bidirectional communication with the robot controller and publish/subscribe messaging with external systems. It is programmed in asynchronous style using pyadept, a Python library based on Python coroutines, AsyncIO event loop and ZeroMQ middleware. The proposed solution facilitates integration of Adept robots into distributed environments and building more flexible robotic solutions with event-based logic.

Abstract (sommario):

Purpose. Development of a control system for a mechatronic system, taking into account the geometric solution of the inverse kinematics problem. The methods. The research was based on the principles of theoretical and applied mechanics, as well as the Denavit-Hartenberg transformation model. The formation of graphical computational models and kinematic diagrams simplified the development of the mathematical model of the dynamic system without considering the forces acting on the mechanism links. The possibility of using matrix transformations to simplify the search for generalized coordinates and transition to the local disposition of each link was explored for further integration of the obtained results into automation and control systems. Findings. The obtained results, determining the trajectory of the gripper using inverse kinematics models, allowed the development of algorithms for determining the position of mechanism links with the possibility of software implementation of the control system. Identifying patterns for determining accurate position coordinates by the matrix method allows the application of open-source software for real-time position calculations. The originality. The use of modern technologies for visual assessment of the external environment and coordinating control impulses of the executive body drive was first achieved based on the mathematical model of the inverse kinematics of a multi-link mechanism. This automated the determination of local coordinates for each link within its degrees of freedom and algorithmized this process. Combining the mathematical models of mechanism kinematics and the matrix form of coordinate search allows investigating the influence of the displacement of the i-th link of the mechatronic technical complex on the overall system, considering the acting force systems and the specified spatial orientation of both the executive body and intermediate links. Practical implementation. The implementation of obtained kinematic models using the matrix method enables the software realization of algorithms for searching the coordinates of the i-th mechanism link, automating the control process with the task of final positions, determining the level of integral error during the displacement of the initial link, and providing the possibility of programming autonomous mechatronic systems with open-source code. As a result, the introduction of semi or fully autonomous technical complexes will automate technological processes in various industries.

Abstract (sommario):

In pace with the technical progress in controllability of mechatronic systems including machines and industrial equipment, the systems of industrial controllers (both PLC and microprocessor ones) more and more frequently use Ethernet-based networks for communication with supervising centres and surveillance systems. The Internet offers unsurpassed opportunities of remote programming as well as remote development, debugging and tuning the existing control software. Nowadays, supporting the remote tools and facilities is the essential requirement that is mandatory when decisions on purchase and implementation of industrial controllers are made. It is the underlying reason to launch more extensive research in that field. The presented paper describes dedicated software that has been developed to enable communication over the Internet within dispersed control systems. The system makes it possible to transmit and to receive short messages to and from the controlled actuators as well as to perform basic tasks related to management of data flow in networks that use TCD and UDP protocols. The special attention was paid to dynamic phenomena of the data exchange process. It is an issue of crucial importance within dispersed systems of industrial controllers and it assures efficient operation of the entire system owing to timely and quick respond to fast-changing control signals. Data exchange was carried out with the use of so-called primitives for Berkeley sockets that serve as primary structures within the network and are capable to perform basic operation such as creation and destruction, assigning network addresses to the sockets, establishing connections, transmission (broadcasting), receiving, etc. To measure time intervals of communication sessions the authors took advantage of functional features of contemporary motherboards of PC computers. In particular, the function of the API counter was used as it allows to readout the fast internal 64-bit counter which, in consequence, enabled measurement of time gaps with accuracy up to single microseconds. The described software performs tests of communication facilities in terms of their applicability to fast data exchange between field control modules of the control system and the CPU, whereas the entire communication is performed via Internet. Therefore the reaction time of a hypothetical field controller in respond to switchovers of the input signals or interrupt events can be measured. The communication and measurements were performed over local and national internet networks as well as for GPRS networks. Measurement results are presented in a compact form of tables that is suitable for further analysis. The presented system is able to transmit diagnostic information therefore it can be also used for integrated diagnostics of mechatronic systems as well as for location and analysis of possible failures within the in-field systems.

Abstract (sommario):

This contribution reports on the progress in the EVA project. This project was started in 2017 based on past experiences made in the framework of workshops and design studios at the University of Applied Arts in Vienna. Within these workshops different concepts toward energy-active and reactive architectural concepts was conceived and realized into scale models. The major design goal was to provide a built structure that is not only energy efficient, but also comfortable for occupants, and can display dynamic behavior in response to stimuli from the surroundings and the occupants. To construct the designs into scale models, different supportive tools and techniques were deployed, such as numeric thermal building simulation, parametric design programming, electronic control loops and mechatronic systems. Moreover, the different designs and concepts were inspired by a wide range of ressources, such as biology, bionics, natural phenomena, and traditional architectural concepts. Partly, these concepts (e.g. the photosynthesis of algae plants) were integrated in the scale models. As such, the workshops and design studios could be considered a success. New, challenging, and exciting designs were developed, and engineered in terms of scale models. However, the proof of concept in terms of real life implementation is missing. This gap will be bridged by the EVA project, which targets the evaluation of different concepts and the realization of the most promising project as a fully functional full scale mock-up. Needless to say, the level of complexity increases by the scale: Aspects of structural and dynamic stability have to be considered, mechatronic elements have to be constructed, and intelligent and reliable building control modi have to be implemented.This paper describes the first phase of this project, which is the collection, description, and structured evaluation of a number of design studies from the past years. Thereby, it was decided not only to assess projects that were designed in the framework of the University of Applied Arts, but to investigate similar design studies from professional and academic backgrounds worldwide The contribution concludes with an outlook of the project’s next steps.

Abstract (sommario):

The article is devoted to the problem of determining the optimal dimensions of the design of reciprocating linear electromagnetic engine. As an optimization criterion, the parameters of the mechatron module based on the multi-output linear electromagnetic motor are determined by means of a constructive calculation scheme and its variable parameters are determined by the method of non-linear programming, the geometric dimensions are simplified, the mass of the electromagnetic motor body, the mass of the motor armature and the masses of the motor stator and the restrictions on their dimensions are determined the issues of finding optimal solutions are considered. Optimization of mechatronic modules based on multi-output linear electromagnetic motors on various parameters leads to increase in dynamic performance of the executive organ, saving energy consumption, and allows to improve performance and service quality. Also, based on the analysis of the existing electromagnetic linear motors, the structural scheme of the mechatron module based on the multi-output linear electromagnetic engines, which allows to perform step movements according to spatial coordinates with high accuracy and speed, is presented. The algorithmic basis of computing is based on the weight and size characteristics of execution mechanisms, and it has been proposed to allow solving optimal design tasks of execution mechanisms taking into account zvenolar lengths, displacements, speeds and accelerations during movement, as well as creating robotic systems with high performance in service. This structure serves to ensure the interaction of the executive body with the object in the links of industrial robots.

Abstract (sommario):

This paper presents control solutions dedicated to a class of controlled plants widely used in mechatronics systems, characterized by simplified mathematical models of second-order and third-order plus integral type. The conventional control solution is focused on the Extended Symmetrical Optimum method proposed by the authors in 1996. There are proposed six fuzzy control solutions employing PI-fuzzy controllers. These solutions are based on the approximate equivalence in certain conditions between fuzzy control systems and linear ones, on the application of the modal equivalence principle, and on the transfer of results from the continuous-time conventional solution to the fuzzy solutions via a discrete-time expression of the controller where Prof. Milic R. Stojic's book [1] is used. There is performed the sensitivity analysis of the fuzzy control systems with respect to the parametric variations of the controlled plant, which enables the development of the fuzzy controllers. In addition, the paper presents aspects concerning Iterative Feedback Tuning and Iterative Learning Control in the framework of fuzzy control systems. The theoretical results are validated by considering a real-world application.

Abstract (sommario):

In the article, using the example of a mechatronic control system for the engine and transmission of vehicles (automobiles), the features of the technology of their diagnosis are shown. In an electronic transmission control system, the object of regulation is mainly an automatic transmission. Also, the laws of control (programs) of gear shifting in an automatic transmission ensure the optimal transfer of engine energy to the wheels of the vehicle (TC), taking into account the required traction and speed properties and fuel economy. At the same time, the programs for achieving optimal traction-speed properties and minimum fuel consumption differ from each other, since the simultaneous achievement of these goals is not always possible. Therefore, depending on the driving conditions and the desire of the driver, using a special switch, you can select the "economy" program to reduce fuel consumption, the "power" program - to improve traction and speed properties, or the "manual" program to switch gears by the driver. In turn, self-diagnostic capabilities include: system identification and electronic control units (ECU) (ECU); recognition, storage and reading of information about static and single malfunctions; reading current real data, including environmental conditions and specifications; modeling of system functions; programming of system parameters. The individual programs for the test block are stored in the plug-in modules, while the correction and data transfer in the system is carried out via the data interface. Note also that the diagnostic process begins with the initialization of the systems - their detection in the electrical equipment of the vehicle. Upon successful initialization, it is possible to: read the error memory; erase the error memory; view the data of the next detected system or exit to the main menu; change the readings of the selected category; correct the current time; correct the current date and perform a number of additional functions.
