Research on the Key Technologies of Network Distributed Flight Control System

In view of the increasing requirement of aircraft survivability on the battlefield and the increasing fault-tolerant level, the paper proposes a network distributed flight control system structure, which constructs a distributed system through distributed network and compute nodes. Several key technologies are discussed following may effectively solve the application problems of network control technology in the flight control system. The health management of compute node is completed by various monitoring means, which also provides data basis for the configuration determination of network control system. System task dynamic coordination and scheduling, combining the resource requirements of system task execution with the resource capabilities provided by system compute nodes, achieve the matching of the two through multiple task scheduling methods. The whole scheme, including the monitoring mechanism of system compute nodes and the scheduling mechanism of system tasks, can give full play to the application of network control technology in the distributed flight control system, so as to support the urgent requirements in system reliability, security and fault tolerance.
