An actuator monitoring system is provided with an electric actuator having a motor and a control unit which outputs a control command (CMD) to the motor to control the operation of the motor. The control unit calculates a use time of the electric actuator based on the control command (CMD) outputted to the motor. Moreover, the control unit estimates the lifetime of the electric actuator based on the calculated use time.
