摘 要: | 本文针对线性最优励磁控制的缺陷,将自适应控制理论与最优控制理论相结合,通过多变量参数辨识、最优反馈系数计算和控制算法运算三个环节,实现了同步发电机励磁的自适应最优控制.数字仿真实验结果表明,该励磁控制系统能够自动跟踪系统运行工况,在线辨识不断变化的系统参数,使控制作用始终处于最优状态,从而改善了控制系统的动态品质,提高了系统的暂态稳定性.

Abstract: | A adaptive optimal excitation control (AOEC) scheme for synchronous machines, conpared with optimal eocitation control (OEC)law,is presented in this paper,The controller is composed of three parts,least-sqrares identification with auto-regulation forgetting factor,optimal feedback parameters calculation and control value output.The results obtaimed by digital simulation show tl1at the new AOEC provides a very good performance, which is superior to that of OEC. |
