MANUAL/POWER-OPERATED HYBRID FLIGHT CONTROL

摘要

PROBLEM TO BE SOLVED: To provide a manual/power-operated hybrid flight control which improves steering feelings without transmitting chatter vibration to a control stick directly.

SOLUTION: The manual/power-operated hybrid flight control 100 controls a rubber 14 mechanically connected to the control stick 10 by subserving manual control forces input via the control stick 10 with power-operated control forces. The control 100 comprises an actuator 13 for driving the rudder by generating auxiliary torque to subserve control torque T input manually via the control stick; a disturbance observer 21 for obtaining disturbance torque D5 acting on the rudder due to disturbance on the basis of the position and the speed of the actuator; and a disturbance variable compensation section for performing disturbance variable compensation so as to suppress the transmission of the disturbance torque to the control stick.
