【 摘 要 】

The unmanned tiltrotor aircraft has many flying advantages, in the meantime it brings some new problems. In order to improve the flight stability of the UAV, the simulation of flight control law reconstruction was designed based on the multi-model adaptive control theory for actuator failure. Using the principle of small disturbance, the linear model of the UAV was established. Aiming at several typical actuator failures, the reconfigurable control strategy was designed. The classical PID control method was used to design the control law structure. Simulation results show that the proposed reconfiguration control strategy can be used in unmanned tiltrotor aircraft, which has good fault-tolerant effects and can significantly improve the safety of aircraft performance.
