PROBLEM TO BE SOLVED: To provide a two-degree-of-freedom control device of high follow-up performance by setting a predistorter optimally also to a control object including waste time. SOLUTION: The two-degree-of-freedom control device is equipped with: a state quantity detection device (106) which detects a state quantity of a control object and generates a state quantity detected value; a predistorter (102) which corrects a state quantity instructed value and generates a state quantity instruction adjusted value; a feedforward controller (101) which generates a feedforward operation amount from the state quantity instructed value; a feedback controller (103) which generates a feedback operation amount from a signal of difference from the state quantity instruction adjusted value and the state quantity detected value; and operation amount controller which makes operation amount follow the operation amount instructed value, wherein the operation amount instructed value is considered as a sum of the feedforward operation amount and a feedback operation amount. The predistorter is variable and the two-degree-of-freedom control device has an automatic adjustment operation part (107) which performs automatic adjustment so that a transfer function of the predistorter may become equal to a transfer function from the state quantity instructed value to the state quantity detected value.
