摘　　要：以功角、有功功率、角速度这些可测量作为反馈量,基于非线性预测控制理论,设计出具有闭合解析形式控制律的励磁控制器.该控制器的设计参数只有滚动预测时间T和控制阶r,便于工程实现和调试.仿真结果表明,该控制器能使系统提高稳定性,具有良好的动态品质,较好地维持了发电机机端电压的静态调节精度.Based on nonlinear predictive control (NPC) theory, a new design method of excitation controller with closed-form analytic solution nonlinear predictive control law is presented. The power angle, the active power and angular velocity are employed as feedback variables. The excitation controller has only two design parameters which are the predictive period and the control order. The simulation results show that the controller can not only improve the power system stability effectively and achieve good dynamic character, but also maintain post-fault generator terminal voltage regulation accuracy.
