Comparative Analysis of SVPWM Based PMSM Using Model Reference Adaptive System

Abstract

 The Electrical system which is known for its reliability mainly prefers AC system over DC due to the stability issues concerning the respective system when DC system is implied into operation. The AC system adjourns the electrical flexibility by providing the required efficiency managing criterion which ultimately gives reason to prefer the respective system over the other. The PMSM is applied in this paper due to several considerations in no particular order like Inertia, dampening the harmonics, stabilizing the system during the operation and most importantly the synchronism within the internal structure. This paper presentsdynamic Mathematical Modelling of Permanent magnet synchronous motor (PMSM) and a space vector pulse width modulation (SVPWM) by using a Model Reference Adaptive System (MRAS). The speed control of the motor is supplied by a three phase two level voltage source inverter. The pulses generated from SVPWM is fed to Three phase two level inverter which possess easy design and ignites a output voltage with has low-frequency and also controlled frequency and amplitude at high-frequency by designing gating pulses.  This paper tend to achieve mainly two purposes; primary one is to estimate the Electrical angular speed and rotor position of the PMSM, The second task is to adjust the motor's speed using the PI controller and the fuzzy controller. PI (Proportional Integral) and Fuzzy controllers (FLC) are employed in this system in order to get the required output speed. The complexity of PI controller, tuning and high response time can be overwhelmed by using FLC which has compact settling time.This is being implemented by using Matlab/Simulink.
