一种基于H_(∞)技术的新型鲁棒励磁控制器

A NewH_(∞)-Based Robust Excitation Controller

论述了微机励磁控制器硬件电路设计及控制规律，微机励磁控制器硬件采用模块化设计，四种控制规律：比例式、比例式＋电力系统稳定器、线性最优控制、基于Ｈ∞技术鲁棒性控制．通过对单机无穷大系统小干扰、大干扰仿真表明，线性最优控制和基于Ｈ∞技术鲁棒控制较前两种控制规律为优，它们不仅能有效的提高系统的静态性能，而且在大干扰情况下，也能够为系统提供阻尼，改善系统的动态品质．

This paper mainly discusses design of H ∞ based robust excitation controller.Through analysis of the conventional controller,a new control strategy is proposed,which can not only enhance the static characteristics of power systems,but also improve the dynamic performance against large disturbance.Furthermore,it is suitable to an extensive area of working conditions.
