【摘要】 本文介绍用80386IBM－PC系统微机直接控制电流跟踪型逆变器及其矢量控制系统的方法。还详细介绍了由并行打印机口作接口提供系统控制的全部数据与控制信号的方法，以及由机内各种资源实现的控制。这种方法与其它类型的微机控制相比，硬件接口简便，软件易于诊断与调试，特别适宜于各类交流调速系统控制方式的开发与研究。更多还原

【Abstract】 This paper intreduces a scheme which uses 80386 IBM-PC computer directly to control current following inverter and vector control system. The parallel printer port interfaces all data and control signals,and different kind8 of hardware and software source in IBM-PC performs the system control. Compared with other types of computer control,this scheme has advantages of simple structure in hardware,easy adjustment and debug in software and is especially suitable for the research and development of new kind control mode of AC motor system.更多还原
