Abstract:
1. A control apparatus comprising: correlation parameter-calculating means for using a controlled object model defining a relationship between a control input and a controlled variable in a controlled object, and thereby calculating a correlation parameter other than parameters included in the controlled object model, indicative of a correlation between the control input and a controlled variable in the controlled object model; target value-setting means for setting a target value as a target of the controlled variable of the controlled object; control input-calculating means for calculating the control input with a predetermined first control algorithm such that the controlled variable of the controlled object is caused to converge to the target value, and determining at least one of an increasing/decreasing rate and an increasing/decreasing direction of the control input according to the correlation parameter; and model corrector means for correcting the controlled object model such that the controlled variable of the controlled object model matches the controlled variable of the controlled object, wherein said model corrector means calculates a plurality of correction parameters for use in correction of the controlled object model such that the controlled variable of the controlled object model matches the controlled variable of the controlled object, wherein the plurality of correction parameters are calculated using a predefined second control algorithm and correspond to a plurality of re ions obtained by dividing a region where the control input is variable, and calculating ones of the correction parameters corresponding to ones of the regions where the calculated control input exists; wherein said model corrector means corrects the controlled object model using values obtained by multiplying values of a plurality of functions by the correction parameters, respectively; wherein adjacent two of the regions overlap each other; and wherein the functions have respective characteristics such that the functions each take a maximum value of one in a center of each of the respective associated regions and change linearly or curvilinearly, and each two of the functions corresponding to each two overlapping ones of the regions are set such that the functions intersect with each other in portions where the functions change linearly or curvilinearly.
