摘　　要：目前 ,电机控制系统中 ,大都采用了PI调节器。PI调节器的参数决定了电机控制系统的性能。至今PI调节器参数的选择还没有一个简单实用的方法。常常是通过不断地反复调试来确定。这样不仅效率低 ,得到的参数也不一定达到最佳。本文介绍了一种利用计算机编程实现在线调节电机控制系统中PI参数的方法。它通过用VC + +编写的上位机程序和用汇编语言编写的下位机程序 ,利用VC + + 6.0中的MSCOMM控件完成了计算机和DSP(数字信号处理器 )之间的通信 ,实现了在计算机上调节电机控制系统中PI参数的功能。At present, the speed control system of the electrical machine includes PI regulators mostly. Regulator parameters affect performance of the speed control system seriously. Up to now there is no simple and practical method for choosing regulator parameters yet, usually they are determined with continual repeated readjustment, so it wastes time and energy and is not sure of optimum. This paper introduces a method of on line adjusting PI parameters in motor control system which is accomplished by computer programming. It realizes the function of adjusting PI parameters of speed control system by PC program written by VC++ and controlling program written by assemble language and by the communication between PC and DSP which is completed by the control MSCOMM in VC++6.0.
