摘　　要：调节器是双闭环调速系统的核心,传统的工程设计方法不仅烦琐、复杂,而且不够精确。为解决上述问题,提出了基于参考模型法的调节器参数优化方法:首先根据系统指标要求选择典型的最佳模型作为参考,然后以改进单纯形法为优化算法,通过比较控制系统和参考模型在同一输入信号下的输出偏差对调节器参数进行优化,使得在某种意义下偏差尽可能小,实现控制系统的输出响应跟踪或逼近参考模型特征。实验表明,方法不仅使设计工作大为简化,并且使控制系统较好地复现参考模型的特征,有效地提高了系统的性能。Controller is the core of the double-loop motor control system,but the traditional engineering design method（EDM） is not only complicated,but also imprecise.This paper introduces a parameter optimization method based on reference model.Firstly,a typical optimization model is set up according to the desired system performance.Then,with an improved Semplex algorithm the controller parameters are optimized according to output bias,which is obtained through a comparision between output response of control system and of reference model subjected to same input signal.Simulation experiments prove that this method not only simplifies the process of design,but also improves the control system＇s performance.
