【Abstract】 As to the high order and strong coupling characteristics of current source inverter( CSI) fed permanent magnet synchronous motor( PMSM) systems,a delay-compensated deadbeat prediction current control( DPCC) strategy was proposed in this paper in order to implement high-performance current control and smooth operation of the motor. The algorithm eliminated the need for capacitor voltage feedback,got rid of voltage sensors,and consequently simplified the computational framework.Meanwhile,the proposed method can reduce the impact of digital control delays on system performance. The designed control strategy was verified by test results of a 48V PMSM drive system.更多还原
