Research on UAV Degrade Control System under Sensor Fault State

In the low-cost Unmanned Aerial Vehicle (UAV), in order to ensure the security of the system and reduce costs, degrade control system under the sensor fault state is becoming more and more highly regarded. Degrade control adopted less sensor configuration to achieve the desired control functions. In the low-cost prototype UAV research and development process, degrade control not only can reduce system configuration, lower system cost and, more importantly, the degrade control of the system ensures security of the system under the fault state. Attitude control is the most commonly used mode in UAV, and this paper will focus on designing of degrade control of attitude control loop.
