摘　　要：研究离散一步时滞系统的鲁棒容错控制。采用带有时滞项的输出反馈控制律,针对传感器和执行器故障进行D稳定容错控制研究,并给出满足D稳定的充分条件,以及控制器的设计方法和步骤。较之单纯的完整性设计在容错的目标方面具有更大的适应性和实用性。仿真实验验证了该方法的有效性。Robust fault -tolerant control in discrete one step time -delay systems was studied. Using the control law with time - delay and output feedback and aimed at the sensor and actuator failures, D - stable fault - tolerant control was studied and a sufficient condition was presented for D stability, then design methods and steps of controller were given. Compared with the simple integrity in the the goals of fault - tolerant design, it is of greater adaptability and practicality. Simulation results were given to demonstrate the effectiveness of the proposed method.
