摘要： 基于模型转换技术,以线性矩阵不等式(LMI)形式建立一类线性中立时滞系统时滞相关稳定性判据,系统的稳定性依赖于时滞大小·给出了时滞相关观测器设计方案·当时滞较小时,提出的稳定性及观测器的设计较时滞无关的结果具有较小的保守性·通过数值仿真显示所得结论的有效性·

Abstract: The design of delay-dependent state observer for a class of linear neutral delay systems is concerned with. Based on the model transformation technique, a criterion of delay-dependent stability is therefore presented in form of linear matrix inequality (LMI), where the system stability depends on the size of time delay. Then, a conceptual design is given to the delay-dependent observer. Compared with the delay-independent results, the state of stability and conceptual design proposed here are both less conservative in case of not long time delays.
