基于LMI的鲁棒PID控制器设计及工业应用

摘要

Considering the widely-used PID controller in industrial process, a LQG-based method of monitoring PID controller performance was proposed to convert the performance evaluation of PID controller and parameter tuning into the linear matrix inequality(LMI) optimization, and then having a licensed software based on this proposed method developed.%针对工业广泛应用的PID控制器,提出一种PID控制器性能评价及鲁棒参数优化的设计方法,该方法将PID控制器性能评价与鲁棒参数整定问题转化为线性矩阵不等式(LMI)凸优化问题进行求解,并利用所提方法开发了工业应用注册软件.
