ABSTRACT:
A motor control apparatus supplies a current to the motor according to the control either by an average current controller or by an instantaneous current controller. The selection of the controller is done by a switching command signal selector, which selects the average current controller when the position deviation is within a specified range, and selects the instantaneous current controller when the position deviation is outside this specified range.
