摘要
在线性最优励磁控制器的基础上，通过模糊推理提出了一种模糊自适应励磁控制器的设计方法．所设计的模糊自适应励磁控制器能根据发电机运行点的变化不断修正自己的参数，从而具有很强的鲁棒性．由于控制器的反馈增益来源于线性最优控制，因此，控制器还具有一定的最优性和稳定性．对一个单机一无穷大系统进行的数字仿真结果表明；用本文提出的模糊自适应励磁控制器能有效地改善系统的劝态品质．
By combining fuzzy control theory and linear optimal control theory, this paPer presents a method for design of the fuzzy adaptive excitation controller by using fuzzy inference. The fuzzy adaptive excitation controller can modify its parameters by thevariety of the operating points of the controlled generator, so it is very robust. Becausethe feed-back gains are obtained by linear optimal control, the controller has someopthoality and stability. Digital simulating results for a single mechine-infinite bus power system show that the dynamic quality of the system is effectively improved by usingproposed contoller.
