Nonlinear Analytical Rules Based Fuzzy Control for the Hydro Turbine Governing System

In this paper, a new fuzzy controller for hydro turbine governing systems is proposed by introducing nonlinear analytical rules into the fuzzy controller. The approach to tuning the rules of the fuzzy controller online is discussed and the parameters tuning method is proposed by comparing the proposed controller to conventional PID controllers. The simulation results show that the proposed fuzzy controller can obviously improve the dynamic performance of hydro turbine governing systems, and strengthen their robustness.
