Vector power propulsion system for cross-domain aircraft and control method

The invention discloses a vector power propulsion system for a cross-domain aircraft and a control method. A propelling shell of the system is installed at the rear end of a cross-domain aircraft, and two propellers are located on the two symmetrical sides of the rear end of the cross-domain aircraft. The inlet end of the proportional overflow valve is communicated between the oil pump and an oil way of the propeller, and the outlet end of the proportional overflow valve is communicated with the oil tank. The method comprises the following steps: establishing a propulsion system control model in two motion modes, inputting a preset input quantity into the control quantity of the system, and outputting the control quantity of the system; and establishing a pose model, inputting the control quantity of the system, outputting the pose output quantity of the aircraft, and controlling the system to operate through the control quantity of the system, so that the aircraft moves under the pose output quantity, and th
