摘要: 研究了一类包含网络诱导时滞、数据丢包以及错序等非理想网络模型的H控制问题。针对以往H控制器设计算法的缺点,通过建立新的差分不等式,提出了一个新的改进算法。新算法具有保守性弱、不需事先给定H范数上界以及不需要计算逆矩阵等特点。数值仿真例子表明,新算法是有效的。

Abstract: The H controller design problem of a class of non-ideal networked control system with time delay,data packet and wrong-sequence is investigated.For overcoming the fault of previous H∞ algorithm,by constructing a new difference inequality,a new improved H algorithm is proposed.In the new algorithm,the upper bound of H norm is not necessarily previously given and the computation of inverse matrix is not needed.Compared with previous algorithm,new algorithm is less conservative.Numerical simulation example shows that the method proposed is valid.

Key words: networked control systems, time delay, Linear Matrix Inequality(LMI), H controller, exponential stability
