状态观测器与控制器的统一设计方法

A Unified Design Method for State Observer And Controller

状态观测器与控制器是自动化装置中比较重要、新颖的两种。状态观测器是在状态检测量不足时用于获取全部系统状态的一种硬（或软）设备，当它与控制器联合应用时，会呈现双环路系统固有的振荡倾向。本文提出一种协调优化的设计方法。

The state observer and controller are new and important automatic instrument.Lacking some state detective means,the state observer is an effective method getting all state information by a hard of soft equipment.When an observer and a controller are simultaneously apllied in control systems,the seesntial oscillatory trend in dual closed loop is shown.A design method coorinating work state between observer and controller is proposed.
