Abstract:
1. A control apparatus including a feed-forward controller configured to perform feed-forward control of a controlled object, the apparatus being configured to obtain a first response data sequence of the controlled object measured by applying a first manipulated variable to the controlled object, and determine, under a condition that a second response data sequence of the controlled object to be obtained in a case where a second manipulated variable data sequence, obtained by respectively multiplying the first manipulated variable by gains as variables which can vary with time, is applied to the controlled object, is expressed as a linear combination of the first response data sequence with the gains as coefficients of the linear combination, the gains so that a discrepancy between the expressed second response data sequence and a target data sequence falls within a tolerance, wherein the feed-forward controller is configured to generate a feed-forward manipulated variable data sequence for the controlled object based on the determined gains and the first manipulated variable.
