摘要
Permanent-magnet synchronous motor (PMSM) are mostly used in high-performance industrial servo applications in which torque smoothness is necessary. The main disadvantage of PMSM is torque ripples, which induce speed pulsations that deteriorate the performance of drives particularly at lower speeds. This paper propose the proportional plus integral controller (PI)working in transient state in parallel with Iterative learning control (ILC) working in steady state with Space Vector Pulse Width Modulation (SVPWM) to suppress the speed ripples in PMSM driven by field oriented control. The speed controller compares the reference speed with actual speed, and thus produce the reference current iq ref value which in turn reduces the speed error. According to iq ref value SVPWM pulses are produced and given to the three phase voltage source inverter. The advantages of the proposed method for speed ripple reduction is designed, analysed and simulated using simulink library in MATLAB R2009a. The results obtained from simulation show the significant reduction in speed ripples using proportional plus integral controller (PI) plug in Iterative learning control (ILC) with Space Vector Pulse Width Modulation (SVPWM). This method shows better speed ripple reduction in comparison with the conventional method. © 2013 IEEE.
