Abstract:

The studies were performed to improve workflow of hydraulic automatic control systems of the tillage units. Tillage quality should not deteriorate. Working bodies of tillage machines have to be moved automatically. Automated devices can be separated into two groups: direct and indirect action. It is preferable to indirect action. The article presents analysis of automatic devices used into tillage machines. Automatic control systems can be hydraulic, electro-hydraulic and pneumatic. Mechanical systems are not effective. Hydraulic systems are cheaper electric and pneumatic. They provide best of energy and quality indicators of technological process of tillage. Automatic control systems are uses draft forces, hitch position, depth of the implement, speed, acceleration and other sensors. Method of computer modeling and optimization of hydraulic automatic control systems of tillage units was developed. Results of computer modeling of hydraulic automatic control systems help to select direction of improving quality and energy indicators of technological process of tillage. Optimized combine implement depth and draft control system of arable unit allow reducing deviation the draft force of the plow; deviation of the depth of plowing is equal to or smaller than agro-technical requirements. Deviation of the draft force was decreased to 13.5 % for deviation specific soil resistance - 20 %, depth of plowing - 0.21 m, deviation of the depth of plowing - 0.019 m (9 %). Deviation of the depth of plowing may be decreased to 0.010 m (4,8 %), but deviation of the draft force shell be increased up to 16.2%. Optimized hydraulic automatic control system of garden tiller with a trapezoidal mechanism leaves smaller untreated soil area from 1.37-1.46 times.

Abstract:

This paper presents the results of the development of automatic control systems for walking dragline excavator digging process. The process enables operational productivity to be enhanced through optimizing digging process. This also prevents extreme loads on machinery and hoist cable deﬂection. The paper also describes mathematical models of the electric drives of the main excavator machinery which form the bucket motion and the model of cable length change. Further the study will analyse the tructure of the control system and the automatic digging algorithm. Computer modeling ﬁndings are also described to conﬁrm the operability of the automatic digging algorithm. Computer simulation of the processes in electric drives of main machinery of a walking dragline in digging operations was performed by means of SimInTech software. The automatic control system optimizes digging trajectory with very fast penetration with permissible overregulation following digging at a constant cut depth. The integrated system of dragline operation process control is practically independent due to the following factors: the automatic digging control system in combination with automatic systems for transporting the loaded bucket to dump and the empty bucket to the face; the automatic main machinery overload protection systems; and the system of control over safe bucket movement in the dragline working space.

Abstract:

Smart cars are the result of the combination of the latest technological achievements in the fields of artificial intelligence, sensors, control science, computer, and network technology with the modern automobile industry. Intelligent cars usually have functions, such as automatic shifting, automatic driving, and automatic road condition recognition. The research of intelligent car technology involves many disciplines. This thesis focuses on the field of smart car visual navigation, focusing on image denoising, image information recognition, extraction, and pattern recognition control algorithms. The traditional trajectory tracking algorithm is mainly used in industrial computer or high-performance computer. The computational complexity leads to poor real-time control, and it is easily interfered by external complex terrain environment and internal disordered electromagnetic environment during vehicle driving. In general, on a regular basis, by the image analysis of the driver or the driver information, the image information is proposed using way trace processing technology, vehicle tracking control method and automatic driving rules. The simulation and experimental results show that the proposed control methods and rules used to carry out automatic driving vehicle are feasible. The algorithm reduces the complexity of the algorithm, improves the real-time and stability of the control and finally achieves a good trajectory tracking effect of the car on high-speed automatic driving.

Abstract:

In the paper the method of integration of production planning and simulation systems has been presented. An automatic generation method of production systems models has been implemented to integrate the Production Order Verification System (SWZ) for multi-assortment, concurrent production planning) and Enterprise Dynamics simulation system. Submitted methodology allowed the direct generation of simulation models for production systems with the use of data obtained from PPC systems, regardless of the production system structure, flow topology of the production processes and the amount of resources and production orders. Generation of simulation models is performed automatically, allowing the omission of time-and labor-consuming process of building a simulation. In the process of generation of the simulation models, methods of data mapping, transformation and exchange, between heterogeneous computer systems (PPC/DES) using neutral formats and data storing (XML) in conjunction with an intermediate neutral data model have been used. The result of transformation is the input file for simulation systems, containing information about the production system model, together with control procedures. Based on the described methodology, operation algorithms have been developed and the computer software RapidSim, that integrates PPC and DES systems has been presented.

Abstract:

This article demonstrates the possibility that robotic systems can automatically design robots with complex morphologies and tightly adapted control systems at a low cost. These automatic designs are inspired by nature and achieved through an artificial coevolutionary process to adapt the bodies and brains of artificial life-forms simultaneously through interaction with a simulated reality. Through the use of rapid manufacturing, these evolved designs can be transferred from virtual to true reality. The artificial evolution process embedded in realistic physical simulation can create simple designs often recognizable from the history of biology or engineering. This paper provides a brief review of three generations of these robots, from automatically designed LEGO structures, through the GOLEM project of electromechanical systems based on “truss” structures, to new modular designs that make use of a generative, DNA-like representation.

Abstract:

As one kind of mobile robots, the automatic guided vehicle (AGV) has been used in more and more applications. Meanwhile, some challenges in this field still exist, which limits the AGV’s further application. One of the greatest challenges is the energy conservation due to AGV’s limited energy-storage capability. Besides, the AGV tracking issue has not been well addressed yet though being studied for over two decades. This work presents an optimal velocity scheme for AGV energy-efficient tracking control, with consideration of both trajectory tracking and energy conservation involved in a nonlinear optimization problem. The proposed controller possesses the easiness for design and universality for kinematics modeling of other wheeled mobile robots. In addition, the controller’s stability and convergence were proved using Lyapunov theory. Finally, the computer simulation results demonstrated the effectiveness of the proposed controller.

Abstract:

A flexible manufacturing system (FMS) is an automated material handling and integrated workstation that is computer-controlled and used for the automatic random processing of palletized parts. To assess the effectiveness of the FMS design before deployments, computer simulation is a cost-effective method. It is crucial to test this simulation software before usage since they have such a clear influence on the FMS decision-making process. A FMS is a complicated, integrated system that includes a central computer numerical control machining center and an automated material management system. The sole drawback of FMS is its greater initial cost and replacement cost if it does not function properly. Therefore, it is important to analyze FMS before installing it. The use of Industry 4.0 technologies has expanded the flexibility of the entire manufacturing system. The development of these technologies, which include the Internet of Things (IoT), big data, artificial intelligence (AI), additive manufacturing (AM), sophisticated robotics, virtual reality, cloud computing, simulation, and others, has increased the industrial system’s adaptability.

Abstract:

Based on the classification of automated driving by the SAE (Society of Automotive Engineers) and the working principle of the ECPBS (Electronically Controlled Pneumatic Brake system), the requirements and the control modes of the APRV (Automatic Pressure Regulating Valve) were concluded. Four structural configurations for APRV were proposed to meet the requirements of the ECPBS. To study the pressure regulating characteristics of the APRV of different structure configurations, a simulation model was established, and a test bench was built. Through experiments, the correctness and the reliability of the simulation model were verified. The pressure regulation characteristics of the APRV of different structure configurations under different control conditions were revealed, and the suitable levels in the SAE automated driving classifications for automatic pressure regulators of different structure configurations were determined; thus, the theoretical underpinning to improve driving safety and develop automated driving was provided.

Abstract:

The paper considers technological control objects whose physical properties, state of aggregation and composition are changed by hydromechanical, physical and chemical effects on the flows of initial substances. The main feature of such objects is their multi-dimensionality, nonlinearity, multiconnectivity, and parametric uncertainty of the mathematical model at the design stage. One of such objects is the chemical reactor with the thermal regime predominantly controlled by single-loop or cascade automatic control systems based on linear algorithms. The main disadvantage of such systems is the problem of maintaining robustness, i.e. stability and control quality under the action of parametric disturbances. In our opinion, the method of analytical design of aggregated regulators (ADAR), developed within the framework of the synergetic control theory, is promising in this sense. The research uses methods of system analysis of technological processes as control objects, methods of the automatic control theory and analytical synthesis of control algorithms based on the synergetic control theory and computer simulation methods. Using the ADAR method, we have solved the problem of algorithmic synthesis of the cascade-coupled control system of the thermal regime of a technological object (chemical reactor) in the nonlinear formulation applying a nonlinear mathematical model of the object. Computer simulation methods have proved the functionality of the «object – control subsystem» complex: system stability, covariance with the set point. It is shown that in the systems controlling thermal processes of the considered type, the heat transfer coefficient parametric uncertainty can lead to an excessive value of the static error, which means that the algorithmic structure of the automatic control system has to be improved. To ensure full robustness of the automatic control system, it is recommended to make the system’s algorithmic structure more complex by introducing an astatic component into the control law and correcting the algorithm tuning parameters.

Abstract:

Chip on film (COF) is a special packaging technology to pack integrated circuits in a flexible carrier tape. Chips packed with COF are primarily used in the display industry. Reel editing is a critical step in COF quality control to remove sections of congregating NG (not good) chips from a reel. Today, COF manufactures hire workers to count consecutive NG chips in a rolling reel with naked eyes. When the count is greater than a preset number, the corresponding section is removed. A novel method using object detection and object tracking is proposed to solve this problem. Object detection techniques including convolutional neural network (CNN), template matching (TM), and scale invariant feature transform (SIFT) were used to detect NG marks, and object tracking was used to track them with IDs so that congregating NG chips could be counted reliably. Using simulation videos similar to worksite scenes, experiments show that both CNN and TM detectors could solve the reel editing problem, while SIFT detectors failed. Furthermore, TM is better than CNN by yielding a real time solution.

Abstract One of the ways to reduce human influence on the control process is the development of automated and automatic control systems. Modern control systems are quite complex and require preliminary ground testing. The article considers the issues of creating Imitation Modelling Stand for such control system synthesis and testing. For this reason, a Control System Model was integrated into the local computer network of the navigation simulator NTPRO 5000. The authors of the paper developed and tested software for information exchange between the navigation simulator and the Control System Model. The authors also developed a functional module of collision avoidance with many targets for testing in a closed loop system with virtual training objects. The results showed that the developed Imitation Modelling Stand allowed developing and testing functional modules of the control systems. In comparison with the found analogues, it is easy to include in a closed simulation cycle various models of command devices, actuators, control objects, objects of training scene, weather conditions; it is universal both for solving problems of manual control and for developing and testing automatic and automated control systems; it is not highly specialised and is created at minimal costs.

Abstract:

Abstract To explore the application of programmable logic control (PLC) in the automatic control of nonlinear machine tools, the application of PLC in the nonlinear electronic system control is studied. First, the author takes PLC technology in the numerical control machine tool electrical control application as the research equipment, PLC technology in the numerical control machine tool electrical control application is divided into four types. Then, according to the need of management number, the overall structure of PLC is designed and developed, and the concept of operation modularization is adopted to realize the decentralized development of PLC. There are three functional modules: repair, compile, and simulate. Finally, the machining performance of the nc system is evaluated experimentally. The processing time difference of two kinds of machine tools is compared. The average processing time of the original (Numerically controlled) NC system is 3.06 s, and the average processing time of the embedded soft PLC system is 2.01 s, with a gap of 1.04 s between the two systems. The Computer Numerical Control (CNC) machining improvement of 1 s is significant in the processing efficiency of CNC machine tools. The numerical control system embedded in the PLC system is more stable in the machining time, so it can be concluded that the numerical control-embedded soft PLC system has carried on some improvements and upgrades to the operation of machine tools. PLC has relatively strong reliability, stability, and flexibility and is widely used in industrial control systems. In the production process of CNC machine tools, the application of PLC can improve the automatic control level of machine tools. The application of PLC can improve the automatic control level of machine tools and realize the effective control of each link in the production process of CNC machine tools, such as the start-stop program, the automatic replacement of cutting tools in the production process, the automatic diagnosis, and treatment of various faults in the production process, which can be realized through the application of PLC technology.

Abstract:

Purpose This paper aims to present the idea of an automatic control system dedicated to small manned and unmanned aircraft performing manoeuvres other than those necessary to perform a so-called standard flight. The character of these manoeuvres and the range of aircraft flight parameter changes restrict application of standard control algorithms. In many cases, they also limit the possibility to acquire complete information about aircraft flight parameters. This paper analyses an alternative solution that can be applied in such cases. The loop manoeuvre, an element of aerobatic flight, was selected as a working example. Design/methodology/approach This paper used theoretical discussion and breakdowns to create basics for designing structures of control algorithms. A simplified analytical approach was then applied to tune regulators. Research results were verified in a series of computer-based software-in-the-loop rig test computer simulations. Findings The structure of the control system enabling aerobatic flight was found and the method for tuning regulators was also created. Practical implications The findings could be a foundation for autopilots working in non-conventional flight scenarios and automatic aircraft recovery systems. Originality/value This paper presents the author’s original approach to aircraft automated control where high precision control is not the priority and flight parameters cannot be precisely measured or determined.

Abstract:

To fulfill the need of operating power systems more effectively through diverse resources, frequency control conditions for maintaining a balance between generators and loads need to be provided accurately. As frequency control is generally achieved via the governor responses from local generators and the automatic generation control (AGC) frequency control of the central energy management system, it is important to coordinate these two mechanisms of frequency control efficiently. This paper proposes a dynamic-model-based AGC frequency control simulation method that can be designed and analyzed using the governor responses of generators, which are represented through dynamic models in the planning stage. In the proposed simulation model, the mechanism of the AGC frequency control is implemented based on the dynamic models of the power system, including governors and generators; hence, frequency responses from the governors and AGC can be sequentially simulated to coordinate and operate these two mechanisms efficiently. The effectiveness of the proposed model is verified by simulating the AGC frequency control of the Korean power system and analyzing the coordination effect of the frequency responses from the governors and AGC.

The article presents the analysis of the automatic control of the bioethanol production process intended for biofuel. It presents the formulated general concept of the system and the method of designing a closed control system based on the iterative prototyping procedure. The modeling and the simulation were carried out in the Matlab®-Simulink environment. The simulation model of the object was developed based on the experimentally registered characteristics. It has been adjusted, i.e. the compatibility of its behavior with the object it reproduces has been confirmed. Based on the tuned model of the object, a control system model was created, which was the basis for computer simulation which enabled the control algorithm parameters to be established. The final verification of the correct operation of the system was performed with the use of hardware simulation. It was based on entering a negative feedback loop of the virtual control system of the real object elements into the loop. The results of the simulation confirmed the correctness of the adopted design.
