变维数非线性切换系统容错控制及其在航天器编队飞行中的应用研究

This project is based on a class of fault tolerant spacecraft formation flying control problem, researches the stabilization and fault tolerant control methods for a class of dimension-varying switched nonlinear systems. By fully utilizing the tradeoff among 1) the state variation rules among modes, 2) the values of initial states and the new states when they just arrive, 3) the switching law, 4) the individual stability and controllers of each mode, a novel fault tolerant control architecture is established...The spacecraft formation flying control problem where the number of spacecrafts may change over the time is deeply researched. Based on the proposed switched system approaches, a new fault tolerant formation control framework as well as its digital simulation platform is provided. This makes the project have the important academic value and practical meaning.
