不确定线性系统的一种鲁棒保稳定最优控制方案

Robust Guaranteed Stability Control of Uncertain Linear Systems

针对不确定线性系统,提出了鲁棒保稳定控制设想。建立了改进的鲁棒回差方程,给出闭环系统鲁棒保稳定的充分条件,以及增益和相位裕度描述形式。同时还给出了相应的鲁棒保稳定控制系统设计方法,并辅以打浆过程鲁棒保稳定控制系统的设计实列和仿真结果。

In this paper, the robust guaranteed stability control of uncertain linear systems is proposed. A robust difference equality is presented.A sufficient condition to guarantee the closed-loop systems robust guaranteed stability is derived.Then a controller design approach for the robust guaranteed stability systems is given. Finally,a design example of refining process is given to demonstrate our results.
