To solve the double propellers synchronous control problem of the buoyancy-lifting aircraft, a control approach which uses cross-coupling method to control the double propellers is proposed. Firstly, the lateral-directional stability and manoeuvrability of this type of aircraft with double propellers are analyzed. Secondly, the cross-coupling control method is used to study the speed synchronization performance of the double propellers to improve the control accuracy. The simulation results show that, the double propellers speed synchronization control system based on the cross-coupling control method has a good control performance and better anti-disturbance. Finally, based on the control theory, the cross-coupling controller of the buoyancy-lifting aircraft with double propellers was designed, and ground run test and flight test are carried out. The experiment results show that the control method proposed has better performance and resistance.
