采用IBM-PC的交流永磁同步电动机宽调速系统

Wide Range Speed Regulation of PMSM with IBM PC

文章介绍了通用微型计算机直接控制电源跟踪型 SPWM逆变器 ,实现对交流永磁同步电动机(PMSM)的矢量控制。当 PMSM在基速以下时 ,实行最大转矩 /电流控制 ,保持恒转矩运行 ;基速以上时能够以最大功率输出。系统的实时控制软件程序采用 Turbo C高级语言编制 ,易于调试 ,修改 。

The paper introduces that the general micro computer controls directly the current tracking SPWM inverter for vector speed regulation of permanent magnet synchronous motor (PMSM). The system operates with the maximum torque/current algorithm in the low speed region and with maximum power output control of the system in the high speed region. The real time control program of the system is written with Turbo C.
