Abstract
A first actuator and a second actuator each have a plurality of control calculation units provided redundantly and a plurality of motor drive units provided redundantly. In the first and the second actuators, the control calculation units of the systems paired with each other transmit and receive information to and from each other by a communication between the actuators. When a failure occurs in any system in either of the two actuators, or when a failure occurs in a communication between actuators in either system, the control calculation unit of each actuator of the system in which the failure occurred stops the motor drive control. Then, the motor drive control is continued by the control calculation unit of the normal system in both actuators.
