The nonlinear system is controlled by using predictive control theory, and this method is applied to excitation control of single-machine infinite system. A control law of nonlinear system with active power, angular velocity and terminal voltage as variables is obtained. The simulation results show that this method can not only improve the stability of the power angle but also improve the dynamic characteristics of the terminal voltage of the generator, which is more effective and practical than the differential geometry method which is considered as the best.
