摘　　要：交流励磁发电机(ACEG)能实现有功功率、无功功率和转速的解耦控制,实现变速恒频发电。交流励磁系统具有多变量、非线性、强耦合和参数不确定性的特点。传统的PID控制难以解决系统非线性问题,矢量控制方法能实现控制变量解耦却依赖具体数学模型。提出一种基于模糊神经网络的解耦控制方法。实验证明该方法能够实现交流励磁发电机变速恒频发电,且方法简单、灵活、方便、有效、鲁棒性强。AC excited generator （ACEG） not only can achieve decoupling control of active power, reactive power and rotating speed but also variable speed constant frequency generation （VSCF）. AC excitation system has the characteristics of multi-variable, nonlinear, strong coupling and parameter uncertainty. The traditional PID control is hard to solve nonlinear problems, while vector control methods can decouple control variables, but dependent on special mathematical models which difficultly reflect changes of generator parameters. A fuzzy neural network decoupling control methods was presented. The experiments show that this method can achieve VSCF generation and the methods are simple, flexible, convenient and effective with robustness.
