摘要
探讨了一类不确定时滞系统的无源控制问题,设计了1个线性状态控制器,使得对于所有可容许的参数不确定性和时间滞后,系统是鲁棒稳定及严格无源的,且时变不确定参数是范数有界的.利用线性矩阵不等式和李雅普诺夫函数方法,得到了不确定线性时滞系统状态控制器存在的充分条件.最后,通过数值例子说明了提出方法的有效性及实用性.
The paper addresses the problem of robust passive control of a class of uncertain systems with time-delay. The problem aims at designing a linear state controller such that, for all admissible parameter uncertainties and time-delays, the controller remains robustly stable and passive. The parameter uncertainties are allowed to be norm-bounded in the paper. Based on a linear matrix inequality （LMI） and Lyapunov function, the conditions for the existence of the desired robust passive controller is derived. In the end, a numerical example demonstrates the validity and applicability of the present approach.
