摘要
综述了空间站一类大型复合航天器的建模与控制方法。首先分析了大型复合航天器的结构动力学特性以及对其进行有效控制所面临的主要困难；然后研究了便于控制系统工程实现的大型复合航天器建模方法；继而对大系统分散控制技术在大型复合航天器控制中的应用前景作了详尽分析，指出分散变结构控制方法和分散协同控制技术在大型复合航天器控制中的优越性；最后还探讨了大型复合航天器控制系统设计中必须注意的一些工程实际问题。
The paper discusses the modeling and control techniques for a class of large compound spacecraft(LCS), such as the space stations. The dynamic characteristic of LCS is analyzed at first, then the difficulties appeared in the control of LCS are discussed, upon which a practical modeling method of LCS suitable for the realization of control systems is proposed. Moreover, the advantages and properties of decentralized control in LCS are analyzed in detail, and the decentralized variable control method is assumed as an efficient techniques in LCS control. At last, several noticeable engineering problems in control system design of LCS are discussed .
