摘　　要：同步发电机输出电压和频率的稳定程度影响供电质量,提出一种用来稳定同步发电机输出电压和频率的模糊—神经控制器。该控制器由2个PI型模糊控制器和2个神经网络构成。采用此方案,降低了模糊控制器比例因子的调整难度。仿真结果表明,该系统在负载剧烈变化情况下具有良好的鲁棒性。Stability of synchronous generator output voltage and frequency has the important effect to the power supply quality. A fuzzy-neuro controller was designed to stabilize the frequency and voltage output of a synchronous generator. The structure of the proposed control system consists of two PI fuzzy controllers and two neural networks. With this control scheme the difficulty of fine tuning the scale factors of the fuzzy controller is reduced. Simulation results show that the system is robust to drastic changes on the load.
