摘要
大型浮空器需要全天候、全时域工作,对其控制系统的可靠性要求高。文中采用多级冗余的设计思想,将控制系统划分为3个层次:逻辑应用层、数据通信层和功能执行层,针对不同层次的关键环节分别采用不同级别的冗余设计。基于不同冗余对象的工作特性分别实施相应的控制策略和算法,包括系统级控制权策略、冗余数据交换策略、冗余处理器仲裁机制以及多冗余传感器融合算法,从而保证各级别冗余设备高度协同受控,最终实现工作控制系统的高可靠性和浮空平台系统运行的高安全性。
Due to the requirement of all-weather and all-day working,large-scale aerostat control system must be high reliable.Based on the multilevel redundancy design thought,the control system was divided into three levels：logical application level,data communication level and function execution level.Corresponding redundancy schemes were designed for the key equipments of different levels.According to different working characteristics of the redundant objects,corresponding control strategies and algorithms,including system control right strategy,redundant data exchange strategy,redundant processor arbitration mechanism and multiple sensor fusion algorithm,were implemented.To ensure that the redundant equipment is highly coordinated,a control system with high reliability and an aerostat platform system of high safety were realized finally.
