Abstract


With the increasingly extensive application of UAV technology, UAV accidents are increasing, and the safety problem
is becoming more and more serious. Therefore, it is urgent to ensure the safety and reliability of UAV. This paper fi rstly introduces the
application requirements and research signifi cance of the fault-tolerant control system of UAV; Secondly, the classifi cation of fault-tolerant
control system of UAV is introduced. Finally, taking the nonlinear system of UAV as an example, the controller and its parameters are
derived, and Simulink simulation model is established with MATLAB software to verify that the designed adaptive fault-tolerant controller
can eff ectively maintain the stability and reliability of the system.

Keywords
