Abstract

Abstract In order to weaken the chattering phenomenon of sliding mode control, a design method of sliding mode control based on the fuzzy switching gain of 3-DOF helicopter is presented. This method hangs together the advantage of fuzzy control and sliding mode control, using fuzzy control to adjust the reach law parameter of sliding mode control. It ensures the robustness of sliding mode control that can weaken the chattering effectively, and it is independent of the accurate math model. Applying the designed fuzzy sliding controller to the 3-Dof- helicopter model, simulation is realized in Matlab /simulink 7.0 environments. The results show that the fuzzy sliding mode control method in the 3-DOF helicopters is valid.
