<P>PROBLEM TO BE SOLVED: To allow suppression of resonance due to spring rigidity of a coupling in an engine bench system having an intermediate shaft and to allow suppression of resonance due to spring rigidity of a clutch also. <P>SOLUTION: A shaft torque detection value T23 is added to a dynamometer torque command value T23ref via a low pass filter (LPF) 21 to obtain a new dynamometer torque command value. A machine model 20 in the engine bench system having the intermediate shaft is replaced by a three-inertia system machine model. A shaft torque control device has a configuration where a dead time element (TD) is used instead of the low pass filter, a configuration where the shaft torque detection value of the dynamometer which has passed the low pass filter or the dead time element is caused to pass a high pass filter (HPF), and a shaft torque controller which performs feedback control of the dynamometer torque command value by the shaft torque detection value which has passed the low pass filter is combined. <P>COPYRIGHT: (C)2012,JPO&INPIT |
