The flight control design of Mini Unmanned Helicopter on sliding mode control

Control system of Mini Unmanned Helicopter is a MIMO system, which is serious nonlinear and uncertain. The flight control design of Mini Unmanned Helicopter has always been a difficult problem. This paper introduces sliding mode control on reaching law to the flight control design of Mini Unmanned Helicopter, and it is the better method to solve this kind of problems. To improve control quality, appropriate reaching law is given. For Mini Unmanned Helicopter given input, the simulation results show that this method can realize fast tracks, and eliminate chattering of control input. This method lays the foundation for flight control design in further application.
