PROBLEM TO BE SOLVED: To provide a valve control device and valve control method, improving the position response characteristic of a valve mechanism with a rotary machine as a driving source, and enabling high response of position response.SOLUTION: By a transfer function from a target opened/closed position &thetas;to a first command, which is constituted by using a mechanical constant 50 of a valve mechanism, the first command corresponding to the input target opened/closed position is calculated; on the basis of deviation between the target opened/closed position &thetas;and a detection opened/closed position, a second command is calculated; and on the basis of the sum of the first command and the second command and the detection opened/closed position, a drive command to a rotary machine is calculated. |
