Abstract: Aiming at the issues of a sensor fault simulation and tolerance technology researched in the hardware in the loop simulation system of unmanned helicopter, a unmanned helicopter flight sensor simulation computer was designed to simulate the signal of air data computer, radio altimeter and GPS. A software fault inject method was introduced and the sensor signals injection was realized. The three sensors fault tolerance programs were designed with VC6.0 and the sensors fault tolerance design of unmanned helicopter was verified. The result shows the availability of unmanned helicopter sensors fault tolerance.
Key words: unmanned helicopter; fault simulation and tolerance; software fault inject; replace tolerance; model tolerance
