Abstract
This article presents a parallel fuzzy PID control strategy on a bulb tubular turbine generator unit for improving the robust control performance. First, the nonlinear model of a bulb tubular turbine generator unit is built in MATLAB/Simulink, and the PID controller parameters are adjusted under rated head. Then, an integrated fuzzy logic PID controller is designed to regulate the hydraulic turbine unit. The effectiveness and robustness capability of the proposed controller are evaluated in four independent experiments: starting process, load rejection, frequency tracking and frequency interference. The experimental results validate that the proposed controller can significantly improve the response performance of the speed of hydraulic turbine units. The coefficient mutation experiment reveals that the robustness of the system has been improved obviously, and unique contributions of the work can provide a reference for the optimal control of bulb tubular turbine generator units.
