Fuzzy immune sliding mode control based hydro turbine governor

To meet the increasing requirements on the performance, a new type of fuzzy immune sliding mode controller(FISMC) for the hydraulic turbine governing system is presented. Controller is finished by incorporating sliding mode control theory, immune algorithm with fuzzy control technology. First, a fuzzy model of the governing system is constructed to represent the local dynamic behaviors of the governing system. A global controller is then derived by combining all local state feedback controllers and a global supervisory sliding mode controller. For improving robustness and tracking performance, immune feedback control is paralleled with sliding mode control. The simulation results show the effectiveness and feasibility of the integrated controller.
