| Summary: | The traditional centralized flight control system architecture is independent of other systems such as electromechanical and mission systems，making it difficult to meet the requirements of modern fighter system comprehensive design. The distributed system architecture with openness and comprehensive control features is an inevitable 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 systems 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 characteristics 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. |
