An Adaptive Fuzzy PID Control of Hydro-Turbine Governor

An adaptive fuzzy control strategy for hydro-turbine governor is presented in this paper. Considering the complex dynamic characteristic and uncertainty of the hydro-turbine governor model and taking the static and dynamic performance of the governing system as the ultimate goal, the novel controller combined the classical PID control theory with adaptive fuzzy control theory is designed. The presented controller is a variable structure type; therefore its parameters can be adaptively adjusted according to the information of the control error. Simulation results show that the proposed control strategy has adaptability, stability and robustness and achieves good performance when applied to a hydro-turbine governing system
