摘要
以含非线性不确定特性和时滞特性的液压伺服控制系统为研究对象,推导了具有非线性不确定时滞系统鲁棒渐进稳定的充分条件,提出了以LMI表示的H∞控制器设计方法,并对此系统进行了仿真,仿真结果表明:所设计的H∞控制器使得系统具有很强的鲁棒性,并且对外部干扰信号具有很强的抑制能力。
Hydraulic servo control system with nonlinear uncertainty and delay was studied. Sufficient condition of robust asymptotic stabilization with nonlinear uncertainty and delay system was given. Design method for H∞ controller with linear matrix inequality was put forward, and simulation was given. It is proved that the system with H∞ controller has very strong robust which has strong ability of resisting the external disturb signal.
