摘要
针对H∞回路成形设计,提出了一种基于线性矩阵不等式技术的PID型权函数优化算法。结合静态H∞回路成形控制器综合,给出了一种系统的鲁棒PID迭代优化方法。基于所提方法设计了蒸汽发生器水位控制系统的PID型主控制器。仿真结果表明,所设计控制系统具有较好的鲁棒性能和鲁棒稳定性,综合控制品质优于全阶权函数优化(或本文所提PID型权函数优化)和标准控制器综合相结合的方法。
A robust PID controller design method was proposed,which was based on PID structured weight function optimization method with linear matrix inequality techniques.By combining static H∞ loop shaping controller synthesis,a robust systematic PID iterative optimization method was given.A PID main controller of steam generator water level control system was designed by using this method.Simulation results show that the control system designed by the given method is of good robust stability and robust performance,and its synthetic control quality is better than the method of full order weight optimization（or PID structured weight optimization mentioned by this paper） combined with normal H∞ controller synthesis.
