METHOD FOR CALCULATING APPROXIMATED OPTIMUM RATIO-INTEGRATION-DIFFERENTIAL CONTROL OPERATION VALUE

摘要

Purpose: it is a kind of for calculate an approximate optimum ratio-it is integrated-method of Differential Control operation value is arranged to obtain ratio, the integrated and Differential Control operation value of a servo motor, so that the operator in a field is easy to use. Construction: calculate approximate optimum ratio-integrate-method of Differential Control operation value in, the ratio control operation value of one present worth is moved into the next value in the positive direction by a moving distance, and the maximum difference between an input value and a real value for Bird's Nest value. If the maximum difference of next value is less than the present worth, next value is set as present worth, and moving distance is arranged by it increases by a magnification ratio to moving distance. If the maximum difference of next value is more than the present worth, present worth is maintained. Moving distance is arranged by increasing by a magnification ratio to moving distance. When the difference between the maximum difference in present and next value is few or when moving distance is very small, at the end of the positive direction of a research ratio control operation value. It repeats identical with that reverse into a research one of positive direction.
