Fault-tolerant Control of Aircraft Rudder Surfaces Based on Pseudo-Inverse Planning and Sliding Mode Control

This paper combines pseudo-inverse planning and sliding mode control to propose a new fault-tolerant control method.In the case of failure or stuck of the elevator rudder, the remaining rudder surface and the thrust angle of the thrust vectoring engine are reasonably allocated, and the sliding mode control is designed to ensure that the actuator quickly tracks the desired rudder output in the presence of disturbances, thus achieving aircraft's safe control.The simulation results show that this fault-tolerant control method makes the aircraft track the desired attitude angle better under elevator rudder failure, and the pseudo-inverse planning is effective.
