Abstract
This testing system is provided with: an input side control device 5 for controlling an input side dynamometer to eliminate a deviation between a speed command signal w1ref and a speed detected signal w1; and an output side control device 6 for controlling output side dynamometer to eliminate a deviation between a torque command signal Tk1 ref and a torque detected signal Tk1. A control gain of the control device 5 is set such that the real part of a pole of a transfer function (w1/w1 ref) 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 device 6 is set such that the real part of a pole of a transfer function (Tk1/Tk1 ref) becomes smaller toward the negative side than the real part of the pole of speed control system closed loop transfer function.
