Abstract
A control device () for this dynamometer system comprises: a feedback controller () that generates a feedback input signal on the basis of a torque detection signal and a feedback command signal; a natural vibration suppression circuit () that generates a correction signal so that natural vibration of a vibration element is suppressed; an inverter input generation unit () that generates an inverter input signal on the basis of the feedback input signal and the correction signal; and a command generation unit () that generates the feedback command signal on the basis of the torque detection signal and a speed detection signal. The command generation unit () generates the feedback input signal from a signal generated on the basis of the speed detection signal and the torque detection signal through band stop processing that attenuates a component within a stop band.
