Current Filtration and Control of Wide-Ranged Speed Regulation AC Servo System

Abstract:

This paper carries research on the methods of wide-ranged speed regulation AC servo system based on the permanent magnetic synchronous motor. The permanent magnetic synchronous motor(PMSM) is a kind of motor with high speed and low rotational inertia, which needs overcoming nonsinusoidal magnetic field，cogging effect and the interference produced by chopper circuit when fulfilling wide-ranged speed regulation. In this paper, the authors analyze the phase current wave of PMSM, and put forth an appropriate type of digital filteration, which is proved true by computer simulation and experimental data.
