摘　　要：在建立交流励磁发电机空间状态方程的基础上,运用逆系统方法将交流励磁发电机精确线性化成有功功率和无功功率两个一阶线性子系统,并运用内模控制算法对其进行优化以提高系统的稳定性。提出了交流励磁发电机的基于逆系统内模控制策略,并进行了仿真实验。仿真结果表明,该方法能够实现对发电输出功率的解耦控制,并具有更高的控制精确度和稳定性。On the basis of AC-excited generator space state equation, inverse system method was applied in the AC-excited generator to make active and reactive power into two first-order linear subsystems. And internal model control algorithm was used to optimize for improving the stability ofthe system. The InternalModel Control （IMC） strategy of AC-excited generator was presented, and simulation experiment was carried out, The simulation results show that this method can realize decoupling control of power generation output power and has a higher control accuracy and stability.
