| Abstract |
Torque ripple induced by current measurement errors in direct torque controlled (DTC) permanent magnet synchronous motor (PMSM) drives is analysed. The focus is on the effect of two phases. It is demonstrated by simulations and measurements that offset error produces a torque ripple component and the fundamental frequency f1 and gain error produces a torque ripple component at twice the fundamental frequency f1. |
