摘　　要：本文将状态反馈线性化的思路应用于交流励磁发电机的励磁控制系统中,得出一套新型实用的交流励磁发电机非线性励磁控制规律。利用该模型通过最优励磁策略对单机无穷大系统进行仿真研究。仿真结果表明,所设计的控制方式能有效地提高系统的动态稳定性和暂态稳定性。Nonlinear excitation controller based on input state linearization theory is proposed in this paper. The control law inferred from the proposed method is used in the excitation system of asynchronized synchronous generator(ASG )?And the simulation of this method based on single machine infinite bus system is presented in this paper?It is proved that this method can improve the system dynamic stability and the transient stability effectively?
