Abstract:
1. A settling judgment method of judging settling of an object to a target position of a positioning control device which performs position control according to a position error between the target position and a current position, comprising: a step of computing the position error for each sample; a first computing step of computing a first judgment value from the position error for each of the samples; a first judgment step of judging whether a sample count, in which the first judgment value becomes less than a first slice value continuously, has reached a first judgment sample count; a second computing step of computing a second judgment value from added position errors of a plurality of samples for each of the samples; a second judgment step of judging whether a sample count, in which said second judgment value becomes less than a second slice value continuously, has reached a second judgment sample count; and a step of outputting AND of the judgment results of the first judgment step and the second judgment step as a settling judgment result, wherein the second computing step comprises a step of computing the second judgment value by adding the absolute values of the position errors of the plurality of samples.
