ABSTRACT:
A controlling method for pulse application to an actuator using a digital controller.
A controlling method of an actuator, wherein a deviation is obtained from a command value and its feedback value, the absolute value of said deviation is determined whether it is larger than the minimum reference deviation corresponding to the dead zone, and only when the absolute value of the deviation is larger than the minimum reference deviation, the actuator is driven by a pulse having an application period proportional to the absolute value of the deviation plus a minimum application period stored in the memory of the digital controller.
The minimum application period stored in the memory is increased or decreased and renewed depending on the judgement whether the movement volume of the actuator at each pulse application was under, proper or over.
