Application of intelligent variable structure control to flexible vehicle

A novel controller, which is called fuzzy sliding mode controller and employs the classical topology, is presented. This paper considers the pitch channel controller design process based on a static-unstable flexible vehicle and proves the system equilibrium state at the origin is stable by using Lyapunov stability analysis method. The fixed point simulation is carried out to check the response characteristics in time domain and the property of tracking command signal. The simulation results show the robustness of the controller.
