器耦合通道控制系统的独立设计方法研究

一些诸如倾斜转弯导弹、三轴稳定卫星等航空航天飞行器存在着较强的通道间耦合作用，使得传统三通道独立设计方法遇到了困难。本文基于变结构控制理论研究了一种新的三通道独立设计思想和方法，并着重从稳定性的角度设计了飞行器耦合通道的控制系统。

A NEW INDEPENDENT DESIGN METHOD FOR CONTROL SYSTEMS OF CRAFTS WITH COUPLED CHANNELS

To some aircrafts and spacecrafts,such as bank to turn missiles and triaxis stabilized satellites,there exist various strong coupling actions among their channels.This makes the traditional 3 channel independent design method which is based on the classical single input control throry face many difficulties.By using the variable structure control theory,a new independent design method is proposed here,in which all the coupling factors among the channels are reserved during the design course and regarded as the disturbances.Based on the method,the control laws of the craft's coupled channel are designed and the determination criterion of sliding mode parameters are also studied.
