Speed control of permanent magnet synchronous motor using matlabsimulink

Speed control of permanent magnet synchronous motor using matlabsimulink / Nur Hidayah Abdul Rahim
Tesis ini memperkenalkan rekaan terperinci sistem pemacu untuk Motor Segerak Magnet Kekal menggunakan Simulink. Rekaan dan simulasi biasanya digunakan untuk mereka bentuk pemacu PM berbanding menggunakan sistem prototaip disebabkan oleh kos. Kaedah ini mengurangkan masa, kos pembinaan prototaip dan memastikan keperluan dipenuhi. Kawalan Berorientasikan Medan digunakan untuk operasi pemacu. Kaedah Kawalan Berorientasikan Medan akan mengawal ruang vector untuk arus menerusi kerangka rujukan dq di rotor. Dengan menggunakan Kawalan Berorientasikan Medan, kualiti kawalan arus tidak akan terjejas oleh kelajuan pusingan motor. Simulasi merangkumi semua komponen yang realistik untuk sistem ini. Pengiraan arus dan voltan dapat dilakukan di bahagian-bahagian yang berbeza di dalam penyongsang dan motor di bawah keadaan stabil. Sistem kawalan gelung tertutup yang mempunyai pengawal Berkadaran Kamilan (PI) di dalam gelung kelajuan telah direkabentuk untuk beroperasi dalam kawasan tork berterusan dan fluks lemah. Perlaksanaan telah dilakukan di dalam Simulink. Skim kawalan Modulasi Lebar Pulsa (PWM) berkaitan dengan pengawal arus telah dilakukan. Keputusan simulasi diberikan untuk dua kelajuan dan dua keadaan; tanpa beban dan beban penuh. _______________________________________________________________________________________________________ The thesis deals with the detailed modelling of a Permanent Magnet Synchronous Motor drive system in Simulink. Modelling and simulation is usually used in designing PM drives compared to building system prototypes because of the cost. This practice reduces time, cost of building prototypes and ensures that requirements are achieved. Field Oriented Control is used for the operation of the drive. Field Oriented Control methods will control the current space vector directly in the d-q reference frame of the rotor. Using Field Oriented Control, the quality of current control is largely unaffected by speed of rotation of the motor. The simulation includes all realistic components of the system. This enables the calculation of currents and voltages in different parts of the inverter and motor under steady conditions. A closed loop control system with a Proportional Integral (PI) controller in the speed loop has been designed to operate in constant torque and flux weakening regions. Implementation has been done in Simulink. A Pulse Width Modulation (PWM) control scheme associated with current controllers was done. Simulation results are given for two speeds of operation and two conditions, no-load and full-load.
