Title:
METHOD FOR ADAPTIVE CORRECTION OF PRESENT VALUE IN VIBRATIONPROOF TEST
Document Type and Number:
Japanese Patent JP3914610
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To obtain a method in which the error between a reference value and an actual present value is corrected automatically and in which the total capability of a corresponding control system can be utilized optimally by maintaining the correlation in terms of time of every force.
SOLUTION: In this method, a signal corresponding to a reference value and that corresponding to a present value are changed into at least one discrete event every time, the signals are limited by two inversion points every time, and a new correction reference value is formed in such a way that the signals are expressed by a first load amount in a first inversion point, by a second load amount in a second inversion point, by the time interval between both inversion points or between points of time of both inversion points and by the shape of a coupling curve between both inversion points and that events which correspond to the reference value and the present value are compared. Then, the correction reference value is used for a control operation instead of the reference value up to now.
