technical field [0001] The invention relates to the technical field of aircraft flight control, in particular to an aircraft cockpit control system and a control method. Background technique [0002] The flight control system of an aircraft is generally composed of a cockpit control system, flight control electronics and actuators. The cockpit control system mainly realizes the driver's control command input, and the flight control electronics mainly realizes the solution of the control law according to the pilot's command. , and output to the actuator for execution; the actuator system deflects the rudder surface of the aircraft according to the instructions of the flight control electronics, and realizes the closed-loop control of the rudder surface.
