球载平台控制系统状态观测器设计

The Design of State Observer for the Balloon-borne Platform

所论球载空间高能天文望远镜平台为七阶系统，为实现最优控制，最好用七个传感器对各状态变量进行测量，为了简化系统结构，该系统只用了两个传感器，其他参量用现代控制中的状态观测器的方法即通过软件的方法实现状态估计。该文给出了系统的状态空间模型、状态观测器的设计方法及估计结果。

This paper introduces a seven stage system control, which is used to control variables for optimal control. In the actual simplified system , only two sensors are used. The other state variables are estimated by algorithm of state observer in modern control theory. In the paper the simulating result and the method of designing state observer and the model of state space is presented.
