Abstract
A servo actuator apparatus has: an actuator which relatively displaces an operation unit on the basis of an input signal E,; a position sensor which detects a relative position of the operation unit and outputs a detection signal D,; an actuator which relatively displaces an operation unit on the basis of an input signal E,; a position sensor which detects a relative position of the operation unit and outputs a detection signal D,; a difference calculation unit which subtracts the detection signal D,from a command signal C,supplied from a flight control computer, to output the input signal E,; and a difference calculation unit which subtracts the detection signal D,from a command signal C,supplied from a flight control computer, to output the input signal E,, where a positive displacement direction of the operation unit is reverse and series to that of the operation unit, and the body units of the actuators are integrally movable, and the actuators can always operate while mutually monitoring the actual operation, and have a function that, when one of the actuators fails and falls in hardover, the other actuator immediately corrects the hardover. In this way, prevention of a hardover or suppression of the degree of a hardover can be realized by a simple configuration.
