Abstract

This paper presents a fully digital control of a PMSM (permanent magnet synchronous motor) servo drive based on dual-CPUs, one CPU is an INTEL 8098 used for monitoring and feedback control of speed, another is digital signal processor TMS320C25, which can implement the precise current control by software. A current predicting method is proposed and tested by simulations. Then two methods of outputting space voltage vectors are presented and compared, Finally, the experimental results of PMSM servo system are given. Simulation and experimental results confirm that this fully digital control system has good performance of speed response
