Research on the fault diagnosis of flight control system

As the core of aircraft, the state of flight control system can impact the survivability and mission effectiveness of the aircraft obviously. The fault diagnosis of flight control system when it breaks down can provide some essential information for subsequent reconfigurable control, which can guarantee the system stability. In this paper, the history and current state of fault diagnosis methods about flight control system are introduced, and then some important methods for fault diagnosis are analysed. Some focus problems on fault diagnosis are also summarized. Finally, an outlook is did for the development tendency of fault diagnosis about flight control system.
