| 英文摘要 |
| This paper is devoted to deal with the attitude control of the quadrotor unmanned aerial vehicle (UAV) with
partial loss of effectiveness of its actuators. After analyzing the dynamic characteristics of the quadrotor UAV, we add the
actuator failures to the system model in the form of multiplicative factor to obtain the dynamic model of quadrotor UAV
with actuator failures. Then we develop a new nonlinear fault tolerant control (FTC) method based on the adaptive sliding
mode control in the case of both unknown external perturbations and actuator failures. The asymptotical stability of the
proposed controller is proved based on Lyapunov method. The real-time flight tests are implemented on the quadrotor UAV
testbed and the results show that the proposed controller has achieved good robustness with respect to unknown external
disturbances and partial loss of effectiveness of quadrotor UAV actuators. |
