Book excerpt: The world’s commercial unmanned aerial vehicle (UAV) industry has witnessed unprecedented boom in recent years. Delighted with an ample supply of this excellent high-tech product, global consumers are paying more attention on UAVs. Civilian UAVs now vastly outnumber military ones, with the estimate of over a million sold by 2016. An UAV has various degrees of autonomy as enabled by the use and precise control of motors. Traditional Direct Current (DC) motors are replaced by permanent magnet synchronous motors (PMSM) associated with the new power electronic inverters. Because of a PMSM’s higher power density than a DC motor, it reduces the rotor losses, thus improving its efficiency. The other improvement comes from the advanced control methods. The simple drive system based on a DC motor with open-loop control is outdated. High frequency switches in power electronic inverters offer an opportunity to change motor input voltage values and frequencies faster than ever before. Vector control approaches are employed with closed-loop feedback control, which brings high precision and good dynamics. Integrated inverter-motor drive systems are in progress. This thesis focuses on how to control PMSM installed in the UVAs with a high performance of dynamic response and fewer speed ripples. Field Oriented Control (FOC) is one type of vector controls to control a PMSM in a quadrotor. FOC of PMSM and Pulse Width Modulation (PWM) are introduced. The simulation results of FOC of PMSM with third-harmonic injection PWM and traditional FOC are compared. This comparison proves that FOC of PMSM with third-harmonic injection provides a better dynamic response for a quadrotor’s movement in vertical direction. In addition, since PWM is helpful to reduce the speed ripples, PMSM has a better steady-state response during operations.

Available in PDF, EPUB and Kindle. Book excerpt: Synchronous motors are indubitably the most effective device to drive industrial production systems and robots with precision and rapidity. Their control law is thus critical for combining at the same time high productivity to reduced energy consummation. As far as possible, the control algorithms must exploit the properties of these actuators. Therefore, this work draws on well adapted models resulting from the Park’s transformation, for both the most traditional machines with sinusoidal field distribution and for machines with non-sinusoidal field distribution which are more and more used in industry. Both, conventional control strategies like vector control (either in the synchronous reference frame or in the rotor frame) and advanced control theories like direct control and predictive control are thoroughly presented. In this context, a significant place is reserved to sensorless control which is an important and critical issue in tomorrow’s motors.

This book was released on 2018 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permanent Magnet Synchronous Motors (PMSMs) have become driving force of various industries. Being high efficiency, high power, low inertia, high steady state starting torque and comparatively simple control methods PMSMs find many applications in traction systems and electric vehicles (EVs). This is the main reason why control strategy research of synchronous motor has attracted a lot of attention. With advancement in power electronics technology and tremendous research over the years on motor control theory, speed control systems of synchronous motor are widely used. Vector Field oriented speed controller that regulates the speed of a PMSM based on Park and Clarke (D-Q transformation) is most famous and widely used to control the speed of various electrical motor drive systems. In this method, a quadrature axis current component developed using speed control provides field oriented vector control. In this project, 400 V four poles, three phase PMSM test bench is simulated using two current controlling techniques – Current Hysteresis Control and Pulse Width Modulation (PWM) control. Based on mathematical equations of PMSM, the dynamic model is designed along with closed loop speed control using traditional proportional-integral-derivative (PID) controller. Also following theory and mathematical equations on Park and Clarke Transformation abc to dq and dq to abc blocks are designed in Simulink. In addition to that, Pulse width modulation (PWM) block and three phase voltage source inverters (VSI) block is designed using Simulink library. As mentioned above simulation using Mathwork’s MATLAB/Simulink package illustrates d-q transformation control of PMSM drive systems using both techniques. Performance of both these techniques is presented along with graphical analysis.

This book was released on 2022-09-27 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2022 in the subject Engineering - General, grade: 12, , language: English, abstract: The creation of a simulation model for closed loop vector controlled IPMSM drive performance enhancement and speed control is described in this book. By regulating the torque component of the current, the model achieves superior speed tracking and rapid dynamic response under transient and steady-state circumstances. The control technique is used by both the proportional and integrated controllers in the PI controller. Combining two independent controllers and reducing the shortcomings of each results in a more effective controller. To offer optimal speed operation in the face of environmental changes, load variations, and structural disturbances, the Fuzzy Logic Controller for PMSM must be properly constructed. Using MATLAB Simulink, this book gives a comprehensive simulation of an internal permanent magnet synchronous motor driving system. Interior permanent magnet synchronous motors (IPMSMs) are used to improve machine performance and offer rapid torque response. IPMSMs are utilised in low and medium-power applications such as servos, robotics, variable-speed motors, electric vehicles, and computer peripherals. Because PM motor drives are becoming more popular, simulation systems capable of handling motor drive simulations are in great demand. Simulation tools can dynamically simulate motor drives in a visual environment, saving money and time and easing the development of new systems.

Available in PDF, EPUB and Kindle. Book excerpt: Classical synchronous motors are the most effective device to drive industrial production systems and robots with precision and rapidity. However, numerous applications require efficient controls in non-conventional situations. Firstly, this is the case with synchronous motors supplied by thyristor line-commutated inverters, or with synchronous motors with faults on one or several phases. Secondly, many drive systems use non-conventional motors such as polyphase (more than three phases) synchronous motors, synchronous motors with double excitation, permanent magnet linear synchronous motors, synchronous and switched reluctance motors, stepping motors and piezoelectric motors. This book presents efficient controls to improve the use of these non-conventional motors. Contents 1.

Download or read book Active Disturbance Rejection Control for Permanent magnet Synchronous Motor Drives written by Lizhi Qu and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fast dynamic response, precise tracking performance, and strong robustness to disturbance are usually needed for high-performance field-oriented control (FOC) of permanent-magnet synchronous motors (PMSMs). Moreover, electromechanical sensors are commonly used to obtain accurate rotor position information for the FOC of PMSMs. The use of these sensors not only increased the cost but also reduced the reliability of the PMSM drive system. To overcome these drawbacks, the development of rotor position sensorless FOC schemes for PMSMs is desired.In this dissertation, based on the active disturbance rejection control (ADRC) technique, three control schemes, i.e., an adaptive sliding-mode current control (SMCC), an adaptive sliding-mode speed control (SMSC), and a robust rotor position sensorless control were developed for PMSMs. In the adaptive SMCC scheme, an extended state observer (ESO) was designed to estimate in real time the PMSM parameter variations, which were treated as the internal disturbance of the PMSM drive system; the control law of the SMCC was then adapted by compensating the estimated internal disturbance. The adaptive SMSC scheme was designed in a way similar to the adaptive SMCC scheme. The core of the sensorless control scheme is a novel enhanced linear ADRC (ELADRC) algorithm consisting of two linear ESOs (LESOs) and a proportional current controller. One LESO was designed to estimate the back electromotive force, which was treated as the external disturbance. The other LESO was designed to estimate the internal disturbances, i.e., parameter and current regulation quality variations. The estimated total disturbance was used as a feedforward compensation term in the current control loops to improve the current regulation quality of the PMSM drive, which further improved the rotor position estimation performance. The proposed three control schemes were validated by experimental studies on two laboratory PMSM drive testbeds. The experimental results showed that the proposed ADRC-based adaptive SMCC and SMSC schemes had a faster dynamic response, more precise current and speed tracking performance, and stronger robustness to disturbances than the existing control schemes. Moreover, the proposed ELADRC-based sensorless FOC scheme had better dynamic performance and was more robust to PMSM parameter variations than the existing sensorless FOC schemes.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The prevalence of permanent-magnet synchronous motor (PMSM) drives in industry applications such as electric/hybrid vehicles has stimulated the need for optimized control methods. Theoretically, the dynamic performance, torque generation efficiency, and robustness are three primary metrics that control methods have sought to optimize. In industry applications, however, the drive’s overall system cost must also be taken into consideration. For PMSM drives, the controller unit accounts for a large portion of the end-product cost and more complicated control methods need more powerful controller units in order to be implemented. Therefore, the PMSM drive can be more affordable if the control methods have simpler structures. Field-oriented control (FOC) schemes and V/f control schemes are most commonly used in PMSM drives. For sensorless PMSM FOC schemes, sliding-mode observer (SMO) is usually adopted to estimate rotor position in the mid- to high-speed range because of its robustness to parameter variations. However, the low-pass filters required in the SMO induce phase delay and cause estimation error which affects the torque generation efficiency. Recently, V/f control schemes are also becoming popular due to its simple structure and wide speed range. They take advantage of stabilizing loops to maintain control system stability without knowledge of rotor position. Therefore, costly rotor position sensors or complicated model based observers are not needed in V/f control schemes. However, the previously proposed stabilizing loops still require much computation effort to guarantee optimal torque generation efficiency. The insulated-gate bipolar transistor (IGBT) based voltage source inverter (VSI) is the standard industry solution for PMSM drives. In order to prevent DC bus short circuit fault, the dead time is inserted in switching signals, which results in current distortion on the other hand. There are previously proposed dead-time compensation methods for FOC schemes to address this issue. However, most of them require extra hardware or complicated signal processing algorithms. In addition, their compensation performance can still be affected by parameter variations. Furthermore, there is no dead-time compensation method which can be conveniently used by V/f control schemes. The goal of this research is to develop optimized control methods with simpler structures to address aforementioned issues, which can be summarized as follows; • develop an improved SMO with a new phase delay mitigation algorithm to reduce estimation error, • develop a V/f sensorless control scheme for PMSM drives with simpler stabilizing loops while guaranteeing the premium performance and optimal torque generation efficiency, • develop dead-time compensation methods which are robust to parameter variations and easy to be implemented and integrated with FOC and V/f control schemes.
