Fuzzy logic enhanced sliding mode control: A case study

The hovering control of a helicopter simulator is studied with fuzzy logic enhanced sliding mode scheme in this paper. The mathematical model of the simulator is analysed and established on aerodynamics, the perfect control is introduced to the sliding mode control and the fuzzy rule base of the designed fuzzy system is established under the principle of Lyapunov's stability theorem. The simulation results show that the proposed control algorithm outperforms the conventional fuzzy logic control algorithm.
