(The hydroelectric generating set is a nonlinear and time-varying system, and the conventional PID control cannot achieve a better control effect. An intelligent PID control method based on genetic algorithm, BP neural network and BRF neural network is proposed. The structure of the intelligent control system, the algorithms of GA, BP, BRF and the mathematical model of the hydroelectric unit are discussed in this paper. The dynamic characteristics of intelligent PID controller and conventional PID controller selected for hydropower unit are analyzed)
