The fuzzy logic controller designed in this study determines the required angular used in the dc chopper control based on motor speed error and its change 设计的模糊控制器以电机的转速偏差及转速偏差率为输入，输出量用于控制斩波调速时的导通角。

The main function of a governor is to monitor the speed deviation of a hydro turbine unit and convert it into the displacement deviation of the servomotor according to a specific characterisic . it is used to control the opening of the guide apparatus and to ensure the unit run steadily at fixed speed under a given load 调速器的主要功用是检测机组转速偏差，并将它按一定特性转换成接力器的行程偏差，借以调整机组导水结构的开度，使机组在给定的负荷下以给定的转速稳定运行。
