摘要：
For linear time-delay systems containing varying parameters, considering problems in practical industrial process control such as time variation of faults and output disturbances, two kinds of fault diagnosis estimators based on state observer are proposed. Based on the two kinds of fault diagnosis estimators, active fault-tolerant controllers are designed by using dynamic output feedback (DOF) control. For the two schemes proposed, we verify the validity by numerical simulations and compare them on the aspects of robust stability, fault estimation error, overshoot and design conservation.
