Study the fault-tolerant design of flight control system based on distributed systems architecture
The traditional centralized flight control system architecture is independent of other systems such as elec-tromechanical and mission systems,making it difficult to meet the requirements of modern fighter system compre-hensive design.The distributed system architecture with openness and comprehensive control features is an inevita-ble trend in technological development.In this paper,the fault-tolerant design for flight control systems based on distributed system architecture is studied.Firstly,the typical system architecture of distributed flight control sys-tems and the objectives of their fault-tolerant design are introduced.Secondly,based on the operational timing and working mode characteristics of the distributed system,a time-based fault-tolerant design is conducted.Finally,based on the composition and system architecture characteristics of the distributed system,a multi-level voting/monitoring surface is designed.By analyzing the running time sequence,composition and architecture characteris-tics of distributed system,the key entry points of fault-tolerant design of distributed system are sorted out,and the solutions and implementation methods of fault-tolerant design scheme are expounded.The engineering practice shows that the fault-tolerant design scheme studied in this paper can ensure the stable and reliable operation of flight control system and effectively improve the system security.
