摘要

A constrainted active model predictive fault-tolerant control strategy against actuator faults for networked control systems with data packet dropout is proposed in this paper. Let N(control horizon) step ahead predictive trace as one unit, then the networked control system is regarded as a switch system, a buffer is designed to reserve the predicted control sequence at the actuator node. When the packet is dropouted, the actuator can choose corresponding control signal. It is shown that the closed-loop networked predictive control system with actuator faults and packet dropout is stabilizable if the corresponding switched system is stabilizable. Finally, simulations are performed to show the effectiveness of the proposed method.
