Robust Finite-Time Tracking for Uncertain Linear Systems with Actuator Faults

الملخص EN

In this paper, a robust finite-time fault-tolerant control (FTC) scheme is developed for uncertain linear systems in the presence of actuator faults.

Since the system uncertainties and actuator faults are unknown, the controller parameters are updated online by the adaptive laws without the need for fault detection and isolation.

It is proved that the proposed state-feedback model reference adaptive finite-time FTC scheme can guarantee that the tracking error converges to a small neighborhood of the origin in finite time.

An application example for an aircraft lateral-directional dynamic system is presented to show the effectiveness of the proposed control scheme.
