Abstract
A control device of a dynamometer system is provided with: a driving force observer which estimates a generated driving force of a vehicle; an electrical inertia control unit which uses the driving force to generate a front wheel basic torque command signal and a rear wheel basic torque command signal; a synchronization control unit which generates a synchronization control torque command signal with respect to the basic torque command signal and the basic torque command signal in such a way as to eliminate a speed difference; and torque command signal generating units which use the synchronization control torque command signal to adjust the basic torque command signal and the basic torque command signal. The synchronization control unit is defined in such a way that the poles of a denominator polynomial of a transfer function from the driving force to the speed difference are all negative real numbers.
