Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adaptive controller and an adaptive control method capable of automatically and easily performing an optimal adaptive control while preventing deterioration in responsiveness, and a control device of injection molding machines.SOLUTION: The adaptive controller performs a feedback control by outputting an operation value u on the basis of a feedback value yobtained by adding a compensation value youtput from a parallel feedforward compensator 4 to a control value y output from a control object 2, and a command value r. The parallel feedforward compensator 4 includes: an identification mechanism 6 for sequentially estimating a frequency response characteristic of the control object 2; and an adjusting mechanism 7 for adjusting the compensation value yon the basis of the frequency response characteristic.
