Abstract :
A new online identification method is proposed to suppress torque-disturbance caused by the harmonics of permanent magnets flux linkage and of current time-delay for the permanent-magnet synchronous motor (PMSM) system. Then, combining with IP control strategy and traditional observing compensation techniques, the authors design a high-performance PMSM servo system. The simulation shows that the designed system has robust servo performance.
