PROBLEM TO BE SOLVED: To provide an actuator control system capable of supplying data on stopping position accuracy of an actuator unit in an inspection and repairing. SOLUTION: A stopping position accuracy control means 121 integrates and stores an occurrence frequency of a corresponding division by determining to which preset stopping position accuracy division its difference corresponds by determining a difference between door opening designating data and actual stopping position data. A position changing frequency control means 122 integrates and stores a changing frequency (an operation frequency of an actuator) of door opening. These integrations are performed in accordance with the actuator unit and the moving (rotational) direction of a control object. A failure occurrence rate calculating means 123 calculates a failure occurrence rate from a frequency falling wide of, for example, a±1 bit range in stopping position accuracy and a changing frequency of the door opening. An output processing means 124 outputs an occurrence frequency (the stopping position accuracy distribution) with every stopping position accuracy division, the changing frequency of the door opening and a failure occurrence rate to a diagnostic analytical device for repairing/inspection.
