摘　　要：给出控制系统的最新发展-网络控制系统的基本概念和典型结构,分析了网络控制系统相对集散控制系统的诸多优点;探讨了航天器底层控制系统采用集散控制系统的现状,并根据现代航天器智能性和自主性的发展要求,指出网络控制系统是未来航天器底层控制系统的发展方向;分析了CAN总线在航天领域的应用,明确了网络控制系统已成功应用到航天领域这一事实;最后通过对网络控制系统及其在航天应用研究现状的分析,得出航天领域迫切需要对网络控制系统的共性问题和航天应用的专有问题进行系统研究的结论。Firstly, the concept and structure of NCS are introduced and the main advantages of NCS are analyzed by comparing with that of DCS. Secondly, the state of using DCS as spacecraft bottom control system is discussed and it is pointed out that NCS will be the future development of spacecraft bottom control system. Thirdly, through the analysis of CAN bus in space field, it is known that NCS had been successfully applied in space field. Finally, the conclusion is given that studying the common problems of NCS and special problems in space field is necessary.
