Decentralized Cooperative Control of Compound Space Station

给出了复合式空间站分散协同控制的基本思想 ,然后针对空间站的特点 ,提出了几种具有不同优化指标的控制指令分配准则。对各种分配准则进行了详尽分析和比较 ,给出了一些有效的结论。分析表明分散协同控制是一种理论上简单、工程上可行的大型复合航天器控制的新方法 ,能够有效地解决复合式空间姿态控制系统的设计问题。

Compound space station (CSS) employs multiple sensor/actuators to implement the attitude control task, which adds complexity into the design of control system. The paper proposed a new control technique named “decentralized cooperative control (DCC)” to avoid these difficulties. The basic conception of DCC was interpreted at first, and then according to the characteristics of CSS, several optimal criteria for control command allocation were formulated and studicd in detail, followed by some useful conclusions. Analysis showed that DCC is an effective solution to the attitude control problem of CSS, which is concise in theory and practical in practice.
