1. An output correcting method in a control system wherein a reverse characteristic having a reverse input/output relationship to a target input/output characteristic of a control object, is preset, and a target value for an output of the control object is calculated, and then a command signal corresponding to the target value is determined based on the preset reverse characteristic, and the command signal is output to said control object, said method comprising:

  • a first step of calculating a command signal corresponding to a given target value for the output of said control object based on said preset reverse characteristic, outputting the command signal to said control object, measuring an output of said control object and estimating a deviation between an actual input/output characteristic of said control object and said target input/output characteristic therefor, and storing data on the deviation between the input/output characteristics as learning correction data, anda second step of reading out the stored learning correction data and correcting the command signal using the learning correction data.
