自动跟踪同期控制系统低阶H_∞鲁棒控制器设计

Low-Order H_∞ Robust Controller Design for Fast Following Synchronizer of Generators System

依据交互投影原理 ,就低阶H∞ 鲁棒控制器设计问题提出了一种具体实现算法 ,进而将其应用于某变频调速电动 发电机组自动跟踪同期控制系统的鲁棒控制器设计。由该算法得到的低阶H∞ 鲁棒控制器所构成的闭环系统性能与全阶控制器相比无明显差别 ,特别是主要性能指标 ,如快速跟踪、无超调及解耦等全与阶控制器基本相同。

In this paper we consider the controller design problem for a fast following synchronizer of a generator system. By using alternative projection technique based low-order H-∞ controller design method, the controller obtained has lower order than those by full order controller design methods and the corresponding closed loop system has expectant performance such as fast following, no overshoot and strong loop decoupling.
