  • Patent number: 12280842
    Abstract: A control device includes a reaction force controller to generate an input torque input to the control target and control a reaction force transmitted from a steering wheel to a steering person, an assist controller to generate a correction torque to correct the input torque based on an output of the control target and a nominal model, and a state feedback circuit to feed back a state compensation value to the input torque based on the output of the control target. The assist controller is configured or programmed such that the transfer function of the control target is constrained by the transfer function of the nominal model in the frequency band where the gain in the gain characteristic of the complementary sensitivity function with respect to the modeling error between the control target and the nominal model is approximately 1.
