Pull digital implementation of high performance current controller

Abstract

Abstracts -The development of fast speed P -processors such as DSP (Digital Signal Processor) makes it possible to implement high performance curmt control algorithm for PMSM (permanent magnet synchronous motor) with software. In this paper DSP-based high performance current controller which includes nonlinear feedback compensation and stationary equivalent of the synchronous regulator is presented. Minimization of harmonic torque ripple due to distorted magnetic wave of the rotor is realized by the measured value of flux wave.
