ABSTRACT:
A hysteresis control method for a control system includes setting an arbitrary reference value for an existing position of a control width and calculating a difference between a present input value and the arbitrary reference value. A direction of increase/decrease from a control value and an input value variation width are calculated. A control value is calculated for the present input value time from the calculated input value variation width and the calculated direction of increase/decrease.
