Key technology research on fault detection and diagnosis for broken-wing small unmanned aerial vehicle

An accident with any component failure of the small unmanned aerial vehicle (SUAV) will happen in the operation process. At present the sensor and actuator faults are mostly studied and the damaged body considers very few. The research status of the air dynamics and fault detection and diagnosis (FDD) are firstly introduced in the paper. The methods of the pneumatic parameters and properties on the broken-wing SUAV and the key technologies of FDD are analyzed. At last the experiment of the broken-wing SUAV is established by using the FDD subsystems. A specific plan and research methods is provided through the paper. Meanwhile it provides the theory and research foundation for reconstruction control system.
