摘要
本文基于Nyquest稳定性准则和扩充频率法,对含有滞后环节的被控对象的系统,提出一个能在微型计算机上实现的、能进行比例、比例加积分(和加微分)的整定参数计算的计算机辅助设计算法.本法使用了寻优技术,能快速求得结果.
This paper studies an algorithm of computer aid design which can be realized on microcomputer and carried on setting parameters computation of P, PI ( and D ) for the controlled plant with delay link based on Nyquest criterion and enlarging frequeny method. This algorithm adopts optimum technique so as to obtain the results quickly
