A robust gain-scheduling control based on VSC and fuzzy local controller network

Based on variable structure control (VSC) and fuzzy local controller network (FLCN), a new design method of robust gain-scheduling control is proposed in this paper. The proper sliding-modes and the tendency-rates for general operation-points are introduced such that the system gets into the sliding-modes’ motion as soon as possible and has the desired performance. Its good performance is due to the robustness of VSC. However, any local controller works well only in the local region of a specified operation-point. In this paper functions similar to the fuzzy-attributed function in fuzzy-systems are introduced to form FLCN. The simulation results showed that the presented method is feasible and acceptable.
