摘要
研究了奇异系统重置观测器的稳定性问题.通过构造李雅普诺夫函数,结合线性矩阵不等式和S-Procedure方法,给出了奇异系统重置观测器二次稳定和输入输出稳定的充分条件.最后数值算例表明了结论的有效性.
The stability of reset observers of singular system is investigated. By constructing Lyapunov functions, this paper provides the sufficient condition of quadratic and input-output stability for reset observers of singular system with linear matrix ine- qualities (LMIs) and S-procedure. Then, a numerical example verifies the feasibility of proposed theorems.
