Turbine governor is the key mechanical equipment of turbine-generator to control the turbine power output. In this paper, a novel variable structure fuzzy logic controller for complex nonlinear time-varying turbine governor is proposed. In this controller, a variable structure strategy is presented for the fuzzy logic controller, which can change its control strategy according to the control errors. This paper has described the structure, implementation and Chaos optimization algorithms based parameters optimization for the proposed controller. Simulation results show that the proposed intelligent controller has good performance.
