Abstract
This testing system is provided with: an input side control devicefor controlling an input side dynamometer to eliminate a deviation between a speed command signal wref and a speed detected signal w; and an output side control devicefor controlling output side dynamometer to eliminate a deviation between a torque command signal Tkref and a torque detected signal Tk. A control gain of the control deviceis set such that the real part of a pole of a transfer function (w/wref) becomes greater toward the negative side than a value obtained by multiplying a resonant frequency by the negative sign, and a control gain of the control deviceis set such that the real part of a pole of a transfer function (Tk/Tkref) becomes smaller toward the negative side than the real part of the pole of speed control system closed loop transfer function.
