Abstract
In order to solve the air-fuel ratio control problem of rotor engine of the UAV in transient conditions,based on the engine mean value model,combined with the actual working process of rotor engine,the intake system dynamic sub-model and fuel dynamic sub-model of rotor engine are established,and then utilized. The feedforward fuel dynamic compensator model is designed based on the inverse model principle,and the compensation effect is simulated and analyzed in Matlab/Simulink. The results show that the compensator model can effectively compensate the fuel injection amount in the transient condition of rotor engine,reduce the maximum deviation of the air-fuel ratio,and shorten the stable adjustment time of the air-fuel ratio.关键词
