Abstract
A control device includes a model following controller in which a transfer function of a control target is restricted to a transfer function of a nominal model in a frequency band in which a complementary sensitivity gain, which is a gain in a gain characteristic of a complementary sensitivity function with respect to a modeling error between the control target and the nominal model, is approximately one. A steady gain of the complementary sensitivity function is about 0.1 or more. A lower limit value of a frequency band in which the complementary sensitivity gain is about one is higher than a first resonance frequency that is a resonance frequency of a yaw rate of a vehicle. A second resonance frequency is higher than the first resonance frequency and lower than a lower limit value of a frequency band in which the complementary sensitivity gain is about one.
