摘要
网络控制系统作为新近出现并兴起的控制系统,其系统结构优秀,能够较好地满足航天器的自主性和智能性的要求,代表了航天器控制系统未来的发展趋势。从网络控制系统共性问题和航天领域专有问题进行了系统地分析,重点讨论航天器总线选用原则、可靠性及拓扑结构、总线负载、总线时延影响因素、通用仿真平台和网络消息调度等问题,并提出了相关的设计和实现方法。
As an emerging control system, network control system can satisfy the demand on intelligence and autonomy of spacecraft by its appropriate system architecture, representing the evolution trend of spacecraft control system. The common issues of network control system and special features of space systems are analyzed systematically. The selection criterions, topology, reliability, system delay, message dispatch and general simulation platforms of communication bus are discussed. Design and realization methods are proposed.
