摘　　要：针对一类状态时滞系统,研究了控制器与故障诊断器集成设计问题。应用H∞鲁棒最优控制方法,在系统存在状态时滞、外部扰动和出现故障的情况下,集成设计控制和故障诊断器,不但能够使闭环系统稳定并且满足一定的鲁棒性能指标,而且同时能够诊断出故障;问题解存在的条件和控制/诊断器的求解方法以线性矩阵不等式(LM I)的形式给出,此方法可以通过M atlab进行方便的求解。最后,通过一个仿真算例来验证本方法的有效性和可行性。This paper considers the simultaneous fault detection and control problem for a class of time - delay systems with both disturbance and faults. Using robust H∞ control theory, the designed controller/detector minimizes the H∞ performance measure when detecting the fault. The sufficient conditions for the existence of controller/detector and the controller/detector design method are presented in terms of linear matrix inequality （LMI）, which can be solved by using some software such as Matlab. A numerical example is finally given to demonstrate the validity and applicability of the proposed approach.
