Fault-Tolerant Control for Carrier Rocket Actuator Based on Adaptive Control with Constraints

A fault-tolerant control (FTC) for carrier rocket with actuator fault using model reference adaptive control (MRAC) method is proposed in this paper. Firstly, the model for the carrier rocket with actuator fault is established by treating the fault as disturbance. Based on the flight dynamic model, the linear quadratic regulator (LQR) technique is used as the basic controller to make the output response follow the command signal. Moreover, in the case of actuator constraints, the fault-tolerant controller is designed using MRAC to minigate the effect of actuator fault with anti-windup compensation. Finally, a numerical example is given to demonstrate the effectiveness of the proposed methods.
