Based on MATLAB, the gray prediction PID excitation control of synchronous generator is simulated and studied. In the simulation, the Parker model is adopted for synchronous generator, which ensures the non-negativity of the gray prediction original data, simplifies the gray prediction algorithm, discusses the processing of gray prediction under steady-state working conditions and the sampling period of raw data, and solves the problem of gray prediction PID control predicting out of control in steady-state conditions. The simulation results show that compared with the conventional PID control, the overshoot and adjustment time of the gray prediction PID excitation control of the synchronous generator are significantly reduced compared with the conventional PID control under different working points, and the control effect is better than that of conventional PID control.
