摘要： Provided is a dynamometer-system dynamo control device that can appropriately suppress the occurrence of resonance phenomena and can realize a no-load state, even in a case where an engine the inertia of which is unknown is connected. The dynamometer system comprises a dynamometer and a shaft torque meter. A dynamo control device 6 in the dynamometer system generates a torque current command signal on the basis of a torque detection signal and a torque command signal. The dynamo control device 6 comprises: a gain calculation unit 62 that multiplies the difference between the torque command signal and the torque detection signal by gain wATR and then by Ki; an integration operation unit 63 that integrates the output signal of the gain calculation unit 62; a high-pass filter 64 characterized by a response frequency wHPF; and a torque current command signal generation unit 65 that generates a torque current command signal by superimposing, onto the output signal of the integration operation unit 63, an output signal obtained by inputting the torque detection signal to the high-pass filter 64.
