Abstract
An actuator is driven by use of a power drive source, while drive output of the power drive source is switched among a plurality of different drive outputs. Values of a physical quantity regarding an operation state of the actuator and a physical quantity regarding energy consumption corresponding to the operation state are detected. One of the drive outputs is selected on the basis of the detected values and in accordance with a predetermined selection method, and the actuator is driven with the selected drive output.
