Streszczenie:

In steam turbine control and actuation, the steam control valve plays a key role in operability and reliability. The electrohydraulic regulating system for the steam control valve, usually called the servomotor, needs to be reliable and high performing under nonlinear excitation interference in actual conditions. Currently, electrohydraulic servo valve control technology is widely used in servomotors. Although this technology has good control performance, it still has some technical defects, such as poor antipollution ability, low energy efficiency, large volume size, and limited installation space. Aiming at the abovementioned technical shortcomings of electrohydraulic servo valve control technology, a servomotor-pump-hydraulic cylinder volume control scheme is proposed in this paper, forming a pump-controlled servomotor for the steam control valve. By analyzing the working principle of the pump-controlled servomotor position control in the steam control valve, the mathematical model of a pump-controlled servomotor for the steam control valve is established. The sliding mode variable structure control strategy is proposed, and the variable structure control law is solved by constructing a switching function. To verify the performance of the proposed control method, experimental research was conducted. The research results show that the proposed sliding mode variable structure control strategy has a good control effect, which lays the theoretical and technical foundation for the engineering application and promotion of pump-controlled servomotors for steam control valves and helps the technical upgrade and product optimization of steam turbines.

The multi AC servomotor synchronous operation control system based on DSP+FPGA and a new intelligent PI controller have been designed. The intelligent PI controller can change the structure of controller and parameters dynamically according to the running status of the system, which improves the dynamic performance of the speed control system. In terms of the condition without loading, the experiments about four AC servomotors in different revolving speed have been implemented and The results of experiments show that the system can achieve the high precision control of the operation of multiple AC servomotors synchronously.

Streszczenie:

The vBow, a virtual violin bow musical controller, has been designed to provide the computer musician with most of the gestural freedom of a bow on a violin string. Four cable and servomotor systems allow for four degrees of freedom, including the lateral motion of a bow stroke across a string, the rotational motion of a bow crossing strings, the vertical motion of a bow approaching and pushing into a string, and the longitudinal motion of a bow travelling along the length of a string. Encoders, attached to the shaft of the servomotors, sense the gesture of the performer, through the rotation of the servomotor shafts, turned by the motion of the cables. The data from each encoder is mapped to a parameter in synthesis software of a bowed-string physical model. The software also sends control voltages to the servomotors, engaging them and the cables attached to them with a haptic feedback simulation of friction, vibration, detents and elasticity.

Streszczenie:

Robotic tasks often exceed the scope of steady-state or periodic behavior, which necessitates generally-applicable models of actuators intended to generate transient or aperiodic motion. However, existing electromechanical models of servomotors typically omit consideration of the switching power converter circuits required for directional, speed, or torque control. In this study, a multi-domain framework is established for switched electromechanical dynamics in servomotor systems for their analysis and control in general aperiodic tasks including transient phases. The switched electromechanical dynamics is derived from the individual models of the internal DC motor, gear train, and H-bridge circuit. The coupled models comprehensively integrate all possible distinct switching configurations of on-state, off-state, and dead time. A combination of cycle averaging with piecewise analytical solutions of the non-smooth dynamics is introduced to handle different temporal scales from high-frequency electrical to low-frequency mechanical variables. System parameters were estimated from experimental data using a dual-servomotor test platform. The model was validated for predictive accuracy against measured data in two distinct tasks—dynamic braking of a pendulum system and sinusoidal trajectory following. The model was also used to formulate the servomotor power consumption, which was implemented for optimal control demonstration and energy analysis. In particular, the servomotor power consumption model provided true optimality (minimization) when compared with the squared rotor torque and the positive rotor mechanical power that are commonly used as proxy models. While the focus of this work is on permanent-magnet, armature-controlled brushed DC servomotors, the approach is applicable to general electromechanical systems with switching-based control.

Servomotors are widely used and well known by hobbyists for control of small scale radio controlled boats, cars or planes. The control is done using a simple PWM signal modulation, easily compatible with a 2 or 4 channels remote control system. As hobbyists are generally simple users, a light knowledge is generally enough to drive this kind of motor. However, in some electronic applications, we need deeper information on servomotors behaviour. Unfortunately, servo manufacturers never give detailed datasheet and no information is available on various WEB sites. Thus, we present in this paper, a SPICE modelling for hobbyist servomotor. Simulation and practical experimentations are done to validate the modelling. Finally, an additional lively 3D modelling is proposed and a concrete didactical application is described before conclusion

Incidents during extracorporeal circulation (ECC) may lead to serious consequences, and troubleshooting exercises are becoming more important. We developed an incident-simulation device operated by remote control for ECC crisis management drills, and evaluated its efficacy at a seminar for perfusionists. This compact device consists of a transmitter and a receiving system and is run by dry batteries without a personal computer. A 4-channel radio-control system is used as the transmitter, and four servomotors placed in a box as the receiving system. To simulate occlusion of 3/8” arterial and venous lines, two servomotors with a rod rotate and the rod compresses the tube. The tilt angle of the stick and the servomotor rotation are in proportion, so that the degree of occlusion is controlled. As a result, the tube lumen becomes “stenotic” and then occluded, depending on the rotation. To cut off the power, the other two servomotors, with a relay system, work as a breaker. When the rod of the servomotor rotates, a micro-switch is turned off. The present device is able to increase perfusion pressure quickly and to simulate inadequate venous drainage quietly. At a seminar for perfusionists, an instructor manipulated the transmitter to create incidents and the participants handled the events effectively. In conclusion, incidents created by this device were perceived as similar to real ECC crises and this device may be useful and educationally effective when used in crisis management drills for perfusionists and trainees.

This paper presents a study on trajectory tracking problem for an AC synchronous servomotor. A mathematical model for the system including AC synchronous servomotor, gearbox, and a load is developed to examine the systems dynamic behavior. The system is controlled by a traditional PID (proportional + integral + derivative) controller. The required values for the controller settings are found experimentally. Different motion profiles are designed, and trapezoidal ones are implemented. Thus, the experimental validation of the model is achieved using the experimental setup. The simulation and experimental results are presented. The tracking performance of an AC servomotor system is illustrated with proposed PID controller.

Abstract The sliding system of machining centres often causes maintenance and process problems. Improper operation of the sliding system can result from wear of mechanical parts and drives faults. To detect the faulty operation of the sliding system, measurements of the torque of its servomotors can be used. Servomotor controllers can measure motor current, which can be used to calculate motor torque. For research purposes, the authors used a set of torque signals from the machining centre servomotors that were acquired over a long period. The signals were collected during a diagnostic test programmed in the machining centre controller and performed once per day. In this article, a method for detecting anomalies in torque signals was presented for the condition assessment of the machining centre sliding systems. During the research, an autoencoder was used to detect the anomaly, and the condition was assessed based on the value of the reconstruction error. The results indicate that the anomaly detection method using an autoencoder is an effective solution for detecting damage to the sliding system and can be easily used in a condition monitoring system.

The article designs a seven joints robot arm using PC-based controller. The system architecture of the robot arm contains seven DC servomotors, seven driver devices and a NI motion control card. The robot arm uses proximity sensors to locate the limit position, and programs motion trajectories to finish assigned tasks. We tune the parameters of the PID controller for the robot arm, and get the nice response to control the robot arm moving to the assigned position. The user interface is developed to control each DC servomotor using Visual Basic. The paper computes the kinematic equations of the seven joints robot arm, and calculates the motion displacement of each joint using inverse kinematic equation. The controller of the robot arm can implement precision point to point motion trajectories, and programs the motion paths on the user interface. In the experimental result, users can program the word type in the user interface. The robot arm catches the pin to write the word in the plane.

This work presents a study about non-continuous sliding modes control applied to Permanent Magnetic AC motor (PMAC), also called AC Servomotor. The two main objectives of this work are: to analise the robustness of the technique related to load disturbance and variations in the windings resistance; and to study alternative ways to reduce chattering. The first part includes a study about the modeling of conventional synchronous motors and PMAC motors, both with salient poles. The aim is to study the models used in the movement control of the referred motors in the synchronous reference frame. The second part presents a study about first order sliding modes control, including a method of high frequency switching (chattering)minimization. Simulation results are presented that confirm the efficiency of the techniques applied. Finally, in the third part we study higher order sliding modes control, aiming at chattering minimization. The concepts developed are those for a 2nd order control. Again, simulation results are presented that confirm the efficiency of the techniques applied.

Robotic arms and hands come in all shapes and sizes, they can be general purpose or task-specific. They can be pre-programed by a computer or controlled by a human operator. There is a certain subsection of robotic hands which try to mimic the shape, movement and function of the human hand, these are sometimes known as biomimetic robotics. This project explores the human robot interaction by creating an anthropomorphic robotic hand with an accompanying exoskeleton. The hand, which consists of a 3D-printed body and fingers, is connected to a forearm where the servos that control the fingers are housed. The exoskeleton connects to the operator's hand allowing finger tracking through a set of potentiometers. This setup allows the operator to intuitively control a robotic hand with a certain degree of precision. We set out to answer research questions in regard to the form and function of a biomimetic hand and the exoskeleton. Along the way, a multitude of problems were encountered such as budgetary issues resulting in only half the fingers having movement. Despite this, good results were gathered from the functioning fingers and our research questions were answered.
Robotarmar och händer finns många former och storlekar, de kan vara för allmänna ändamål eller uppgiftsspecifika. De kan programmeras av en dator eller styras av en mänsklig operatör. Det finns en viss typ av robothänder som försöker efterlikna formen, rörelsen och funktionen hos den mänskliga handen, och brukar kallas biomimetisk robotik. Detta projekt utforskar interaktionen mellan människa och robot genom att skapa en antropomorf robothand med tillhörande exoskelett. Handen, som består av en 3D-printad kropp och fingrar, är ansluten till en underarm där servormotorerna som styr fingrarna sitter. Exoskelettet ansluts till operatörens hand vilket möjliggör spårning av fingrarnas rörelse genom ett antal potentiometrar. Detta tillåter operatören att intuitivt styra en robothand med en viss grad av precision. Vi valde att besvara ett antal forskningsfrågor med avseende på form och funktion av en biomimetisk hand och exoskelettet. Under projektets gång påträffades en mängd problem såsom budgetproblem som resulterade i att bara hälften av fingrarna kan kontrolleras. Trots detta fick vi bra resultat från de fungerande fingrarna och våra forskningsfrågor kunde besvaras.

This project explores the possibility to stabilize a hand held serving-tray using a micro-controller, two servomotors and an inertial measurement unit (IMU). It is heavily focused on control theory, specifically using a PID controller. Stabilization of an object using a PID controller have many applications such as drones, camera stabilizers and flight simulators. The report covers the theory necessary to construct a self stabilizing platform and describes involving components in the prototype and how they cooperate. With the gyroscopes and accelerometers involved in the IMU it is possible to determine orientation and rotation of the tray. The construction enables rotation about the x-axis (roll) and y-axis (pitch) but not the z-axis (yaw). The readings from the gyroscopes and the accelerometers are combined and filtered through a complementary filter to estimate the rotations. The servomotors compensate disturbance in keeping the platform horizontal through PID regulation. The PID constants are tuned through tilting the platform at a specific angle and plotting the step response in MATLAB.
Detta projekt utforskar möjligheten att stabilisera en handhållen serveringsbricka med hjälp av en mikrokontroller, två servomotorer och en tröghetssensor (IMU). Projektet lägger mycket fokus på reglerteknik, specifikt att använda en PID-regulator. Stabilisering genom PID-reglering är användbart i många olika produkter, exempelvis drönare, kamerastabiliserare och flygsimulatorer. Rapporten täcker relevant teori för att konstruera en självstabiliserande plattform och beskriver ingående komponenter i prototypen samt hur de samverkar. Med gyroskopen och accelerometrarna som finns i IMU:n är det möjligt att uppskatta position och rotation för ett objekt. Konstruktionen tillåter rotation kring x-axeln (roll) och y-axeln (pitch) men inte zaxeln (yaw). Mätningarna från gyroskopen och accelerometrarna kombineras och filtreras med hjälp av ett s.k. complementary filter för att uppskatta rotationen av objektet. Servomotorerna används i sin tur till att hålla plattan horisontell genom att kompensera störningar från omgivningen. Detta görs genom PID-reglering. Konstanterna i PID-regulatorn är framtagna genom tester där plattformen lutas ett bestämt antal grader och stegsvaret plottas i MATLAB.

Using neural network model instead of a traditional PI controller to control servomotor speed is proposed in this thesis. Firstly, a back propagation neural network is trained by sampling data, and its important parameters are optimized. There are three parts: training program, testing program and system program in our training network. From training program, the characteristic of back propagation neural network makes every neural node strength and weight value of processing unit bias to learn and adjust itself according to an error adjusting value. An error convergence diagram detects convergence of the program. The optimum weight value will be acquired until program converges. Then, runs the value by testing program. Errors between sampling values and output values are going to be compared. Finally, we take the optimum weight value into system program and acquire a real output control signal and speed response. Comparing speed response between a neural network controller and fixed gain controller, the method that we study in the thesis can reach to a steady speed more quickly. And such substitutive result can simplify a controller design. Computer simulations demonstrate that the proposed control method can obtain a robust speed control.

This thesis presents the design procedure and hardware implementations of intelligent controllers for ac servo motors based on artificial neural networks and digital signal processor based systems. Three control structures, i.e. neural networks plus PI, neural networks plus iterative mode and neural networks plus sliding mode controllers, have been investigated in this thesis. A three phase ac permanent magnetism synchronous motor is selected for the control target and for the evaluation of control performances in terms of variations in system operating conditions and parameters of the controlled motor. Comprehensive simulation and experimental studies have been carried out to compare the effectiveness of the proposed neural based controllers with the conventional PI controllers in terms of speed tracking errors and robustness indices when a randomly appear or periodic disturbance is encountered. For the purpose of simplicity and providing flexibility in testing various control structures several complex computational and signal processing tasks, e.g. the coordinate transformation, the generation of SVPWM signals, the flux estimation, the calculation of rotor electric angle, AD/DA conversions and two internal PI controllers are accomplished using the TI DSP2812 chip. The simulation tasks and hardware implementation of controllers with various test examples are carried out via a personal computer, DSP and the VisSim software environment. Both simulation and experimental results are presented to prove the feasibility and superiority of the proposed control schemes.

The results and comparison of controller performance based on fuzzy logic and neural networks with the purpose of improving the performance of PID controllers currently used in servomotors is presented. The performance comparisons will be made with no load and with load (consisting of a robotic type rotational link). The results show that as the number of links in a robot increases, the precision of the movements desired from it decreases, affecting the tasks that require a high degree of precision, so the design of controllers like those presented in this chapter is required. This work is the basis for implementing improvements in the performance of DC servomotor control systems in general.

The proposed work is to design an Arduino-controlled two-wheeled Bluetooth robotic arm for control purposes. The arm mechanism works either by an outdoor user or by preset command. The medication and trade fields are the most developed field regarding the usage of this technology. The design will allow our robotic arm to exercise in four different axes (directions) with four servomotors. It can also take the objects from one place to other with the help of the geared motors and wheels attached to the holder. And jointly combines and works it with the fabric it receives. This mechanism is controlled with the help of the automation application controlled with the help of the HC-05 Bluetooth module linked to the Arduino Uno. The code is programmed to manage the working of servomotors. This design is similar to some robotic cranes, or we can turn it into a robotic crane with some adjustments. It is highly used in the manufacturing plants, Industrial sector for Automation, Agricultural and medical fields.

This chapter is about a basic power-efficient object dropping game named “Catch Me If You Can,” which works on the Arduino platform. A dropping mechanism is developed using the servo motors interfaced to Arduino. The mechanism includes an object holder attached to the servomotor and a loading tube. The dropping of the objects is controlled by any wireless Bluetooth controlling device like a mobile phone or joystick and by the keypad interface installed in the design. The game is about catching the objects dropping randomly as a challenge which is controlled by the operator. The overall simulated design can be done in EasyEDA platform. The overall game can be controlled by an app which is designed by MIT App Inventor. This game can be implemented in Amusement parks, exhibitions, kid schools, and shopping malls. Besides this entertainment aspect, commercially it works as a small-scale product packaging system by involving DC motors, which are needed in moving packaging belts. This mechanism is efficient in packaging products in some specific count.

The domain of flexible robotics is gaining momentum due to its widespread advantages despite major technological barricades, such as in-situ vibration and joint instability. Flexible robotic system (FRS) pertains to unique designs of serial-chain assistive robots that exhibit the said inherent vibration impromptu. This chapter focuses on the control system algorithm of a prototype serial-chain FRS (PARv1.0), backed up by the indigenous firmware of the system controller and run-time software. The chapter also brings out the parametric relationship of the control system hardware over the electromechanical output of the FRS. The design function architecture of the prototype multi-degrees-of-freedom FRS, highlighted in this chapter, is a rare combination of three revolute and one prismatic (RRRP) joints intended for pick and place applications, having a 1500 mm radial span reach in the horizontal plane. A prototype miniature gripper actuated by a mini-servomotor is another novel development of this FRS.

Valve-controlled electro-hydraulic actuators in a Stewart platform configuration have become established as a good way of meeting the performance required for flight simulator motion systems. However, valve-controlled actuators are very inefficient, and thus an electrohydrostatic motion system, controlled using servomotor driven pumps, has been developed by Thales, and is now in production. This paper presents a simulation study of a multi-axis controller which can improve the dynamic response of the new motion system. A modal control approach is used — i.e. the modes of vibration of the system are controlled individually. These modes are dependent on the inertial properties of the platform and the compliance of the actuators. The modes change as the motion system moves throughout its workspace, and so the controller has to adapt to the current operating point. Simulation results are presented based on a partially validated model of the motion system.

Streszczenie:

A fast, accurate and robust position controller is proposed for a planar three degree of freedom robot arm actuated by rotary Shape Memory Alloy actuators and servomotors. Servomotors are used to actuate the first link and the gripper, while the remaining two links are actuated by a combination of shape memory alloy wires and pulleys. Initially, a model of the robot arm is developed for theoretical controller development. The model combines robot kinematics and dynamics with the SMA wire heat convection, constitutive law, and phase transformation equations. The model is then used to develop several nonlinear position controllers based on the Variable Structure Control, also called sliding mode control. The controller development is of an evolutionary nature starting from a simple switching control based only on position feedback and then adding velocity and integral feedbacks, respectively. Several simulations of the proposed controllers are presented. Several experiments have been performed with a desktop prototype of the robot arm. The experimental results verify the effective and accurate performance of the controllers despite significant modeling inaccuracies and parameter uncertainties.

Stochastic computing (SC) provides a fault-tolerant and low-cost alternative to conventional binary computing (BC). The capacity of SC to implement complex mathematical functions with simple logic gates creates a path toward the design of efficient hardware architectures. This paper presents a new methodology for the hardware implementation of servomotor controller using SC. We design SC circuits using both quadrature decoder and efficient decoder for implementing servo controller and compare them with traditional BC-based servo controller. The quadrature decoder requires more hardware resources than efficient decoder but can provide position information in PWM form. The FPGA implementation result shows that, compared to BC-based design, quadrature decoder-based design achieves 56.7% savings in area and 33.33% savings in power consumption, and efficient decoder-based design achieves 73.7% savings in area and 33.33% savings in power consumption.
