Research on Control Strategy of Fixed Wing UA V with Multiple Power Sources Based on Logic Threshold

A complete cruise mission of the UA V with multiple power sources contains five mission stage, that is engine starting, acceleration skating, acceleration climbing, gliding and landing. For the different mission requirements of typical flight courses of the UAV, the aviation engine optimization control strategy based on logic threshold and the electromotor revolving velocity control strategy based on fuzzy compensation were utilized to optimize and control the aircraft. The necessary output power of the aviation engine and electromotor can be worked out by intelligent optimization algorithm in order to accomplish the reasonable flow among fuel, battery and capacitor under certain expected power requirements by simulation.
