摘　　要：应用自适应模糊比例积分微分（ＰＩＤ）控制理论及非线性寻优方法，结合电力系统实际情况设　计了一种发电机　励磁电压调节器。它能根据现场采集的数据以及给定的性能指标实现模糊参数。模糊规则实　时自动调整，以期获得快速。优化的励磁调压控制。数字仿真研究结果表明，该调节器具有　较强的自适应性和鲁棒性，控制效果比晶闸管励磁调节器要好，且能有效地改善系统的稳定　性能。Applying adaptive fuzzy PID control theory and nonlinear optimization method and considering the practical situation of power system, a generator excitation reg ulator is developed. According to the on-site data and the specifie d technical index the regulator can perform automatic regulation of fuzzy parame ters and fuzzy rules to realize the fast and optimized excitation control. Digit al simulation shows that this regulator possesses good adaptability and robustne ss, its control effect is better than that of thyristor excitation controllers a nd with it the stability of power system can be effectively improved.
