Abstract
A control device includes: a static compensator that calculates, on the basis of a static parameter, a static compensatory input; a dynamic compensator that calculates, on the basis of a dynamic parameter, a dynamic compensatory input; a subtractor that calculates an actual input by synthesizing the static compensatory input and the dynamic compensatory input; an ideal output calculator that calculates an ideal output responsive to a control input by using an input and output model defining an ideal input and output relation between a control input and a control output; and a parameter adjuster that adjusts the static parameter and the dynamic parameter to minimize a difference between the control output and the ideal output.
