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.

本文提出了一种用于灯泡管状涡轮发电机组的并行模糊PID控制策略，以提高鲁棒控制性能。首先，在MATLAB / Simulink中建立了一个灯泡形涡轮发电机组的非线性模型，并在额定扬程下调节PID控制器参数。然后，设计了一个集成的模糊逻辑PID控制器来调节水轮机单元。在四个独立的实验中评估了所提出控制器的有效性和鲁棒性：启动过程，负载抑制，频率跟踪和频率干扰。实验结果验证了所提出的控制器可以显着提高水轮机转速响应性能。
