摘要

本文提出了一种基于双CPU的永磁同步电机伺服驱动器的全数字化控制方法，其中一个CPU是用于速度监测和反馈控制的INTEL 8098，另一个是数字信号处理器TMS320C25，它可以通过软件实现精确的电流控制。提出了一种电流预测方法，并通过仿真进行了验证。然后给出了两种输出空间电压矢量的方法并进行了比较，最后给出了永磁同步电机伺服系统的实验结果。仿真和实验结果表明，该全数字化控制系统具有良好的速度响应性能。

Fully digital control of PMSM servo drive using DSP

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.<>
