摘要
针对一类Markov跳变系统,构造一个跳变的输出观测器,以获取故障信号的残差信息.对重构的观测器系统,在残差特性稳定性分析的基础上,故障信号为平方可积的有界信号时,可灵敏地检测出故障.文中在给定的性能指标下,设计出了满足上述要求的观测器,并给出了仿真算例.
The dynamics of residual generator is obtained by constructing a jump observer for a class of Markov jump systems. As to the reconstructed observer system,the fault of the system is sensitively detected while considering the stability analysis of the residual fault and the bound of the fault signal,which is square integrable. Under the given performance index,a proper observer is obtained to satisfy the requests above and a numerical example is proposed.
