摘要:针对以往文献中的迭代学习励磁控制器都是基于单一目标而设计的,存在不能同时完成多个任务的缺陷,提出了双重学习励磁控制方案,以解决同步发电机励磁控制系统的多目标控制问题。该方案将迭代学习的机端电压补偿和角速度补偿结合起来,并分别与两种基于单一目标而设计的迭代学习励磁控制器作了对比研究,仿真结果表明,所设计励磁控制器不仅能很好地解决发电机机端电压的控制精度问题,而且有效地改善了系统的功角稳定性。

The scheme integrates terminal voltage and rotor angular velocity compensations based on iterative learning control (ILC), and was compared with two excitation controller based on single objective respectively. Simulation results show that the designed excitation controller can eliminate the problem of the terminal voltage deviating, and improve the power angle stability.
