| Abstract: | To minimize the low speed torque ripple of permanent magnet synchronous motor(PMSM) used in high-performance servo system,the traditional torque ripple suppression methods were discussed,the main components of torque ripple were analyzed and its periodic characteristic was pointed out.Based on these,a new method using iterative learning control(ILC) was proposed to minimize the periodic torque ripple of PMSM with constant voltage frequency ratio control.The method minimizes the torque ripple by on line lear... |
