摘　　要：考虑参数不确定时滞系统的鲁棒容错控制问题。为设计输出动态反馈控制器,使得闭环系统在传感器发生故障时仍能保持渐近稳定。基于一种传感器故障模型,通过在解析过程中使用非线性变换和锥补线性化方法,得到了与时滞相关的动态输出反馈鲁棒容错控制器存在的充分条件,并给出了控制器参数的显式表示。通过仿真算例验证了结论的正确性和有效性。To design the output feedback controller which guarantes the asymptotically stability of the closed-loop system with sensor failures, the fault-tolerant control for time-delay systems with parameter uncertainties and sensor failures was considered. Based on the sensor model of failure, the nonlinear transformation and the cone-complementary linearization iterative algorithm were introduced in the computation. The delay-dependent sufficient criterion for the solvability was established in terms of LMIs, from which the desired controller could be explicitly formulated. Finally, a numerical example was presented to illustrate the effectiveness of the proposed approach.
