To reduce the deviation of learning and to accurately control a controlled object by combining partial learning and overall learning so as to minimize the influence or not to interfere with each other between the partial learning and the overall learning.

A control part 53 calculates a manipulated amt. from an operation condition, a control parameter and an overall correction coefficient and outputs it to a controlled object 54. A learning model 52 computes the control parameter from the operation condition and outputs it to the control part 53. In a correction amount computing part 55 of a partial change, a correction amount is computed so as to reduce a difference between a target value and an actual output value, the control parameter is corrected and the learning in the learning model 52 is performed, based on the parameter. In the meantime, in a correction amount computing part 56 of an overall change, the correction amount is computed so as to reduce the difference between the target value and the actual output value, the overall correction coefficient is corrected, the overall correction coefficient is fed back to an overall correction part 57 and the learning is performed. The overall correction coefficient is used for the correction of the manipulated amt. in the control part 53.
