Abstract
A method and apparatus for automatically adjusting an operation time of a servosystem into a predetermined allowable range, either from the outside or from the inside. An average operation time of the servosystem is calculated and then an amount of level shift is calculated from the resulting average operation time. Based on the resulting level shift, the operation time of the servosystem is stepwisely shifted at a given time interval. After the shift, an average operation time of the servosystem is calculated again. This is repeated until the average operation time enters the allowable range.
