飞行器控制的伪线性系统方法——第一部分:综述与问题

Quasi-Linear System Approaches for Flight Vehicle Control——Part 1: An Overview and Problems

首先将非线性控制方法归纳成三类:基于李雅普诺夫泛函的设计方法、基于最优控制思想的设计方法和以线性为主导的设计方法,并对此三类方法进行了简略的综述。然后进一步在此类划分的框架下概述了飞行器控制的非线性方法,并引入了伪线性系统的概念。最后介绍了卫星姿态与轨道控制、飞行器制导与控制中的六类典型飞行器控制问题的二阶伪线性系统描述。

This paper firstly classifies the nonlinear control approaches into three categories:the approaches based on Lyapunov function selection,the approaches based on optimal control schemes,and the approaches based on linear approximation and domination,and gives a brief overview on each category.Along with this classification,an overview on the nonlinear flight control approaches is also provided,and the concept of quasi-linear systems is then introduced.Finally,the second-order quasi-linear system descriptions of six typical control problems arising from the fields of satellite attitude and orbit control as well as vehicle guidance and control are provided.
