GA-based fuzzy sliding mode governor for hydro-turbine

This paper presents a novel approach for speed governing of hydro-turbine by means of a sliding mode controller. For selecting a group of parameters of the sliding surface, genetic algorithm is employed to search these parameters. For decreasing the chattering problem of the sliding mode controller, a fuzzy interface system is harnessed to regulate the controller gain. To verify the feasibility and robustness of the control method, simulation results from a hydro turbine unit with the controller designed by the presented procedure are given as an illustration.
