Abstract:
1. An adaptive value generating apparatus for generating an adaptive value for controlling an object under a predetermined control condition, comprising: a statistical processing device for executing a statistical process when a set of an input value and an output value and a function including at least one parameter are designated, thereby determining a value of the parameter so that a calculation value of the function corresponding to the input value comes close to the output value and generating an approximation expression; and an adapting device for determining an approximation function for estimating a state of the object, outputting information designating the determined approximation function to the statistical processing device, outputting a measurement value, which is obtained by measuring the state of the object under the predetermined control condition, as the output value and the predetermined control condition as the input value to the statistical processing device, evaluating precision of the approximation expression on the basis of the calculation value and the measurement value when the approximation expression is received from the statistical processing device, and generating the adaptive value by using the approximation expression in the case where an error is within a predetermined range.
