description A control device, an electric power steering device, and a control method, the control device being provided with: a reaction force control unit that generates an input torque to be input to a control target and controls a reaction force to be transmitted to a steer; and an assist control unit that generates a correction torque that corrects the input torque on the basis of the output of the control target and the nominal model. The assist control unit has: a high-pass filter having a first cutoff frequency; a low-pass filter having a second cutoff frequency higher than the first cutoff frequency; and an interference compensation value calculation unit that, when the transfer function of the low-pass filter is set as Q (s) and the transfer function of the high-pass filter is set as HPF (s), restricts the transfer function of the control target as the transfer function of the nominal model in a frequency band in which the gain of the gain characteristic of Q (s) HPF (s) is 1. The disturbance compensation value
