Title:
TESTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/255505
Kind Code:
A1
Abstract:
This testing system is provided with: input side and output side dynamometers coupled to a test piece having a transmission ratio g that can be changed; an input side control device 5 for controlling the 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 the output side dynamometer to eliminate a deviation between a torque command signal Tk1ref and a torque detected signal Tk1. A control gain of the input side control device 5 is set such that the real part of a pole of a speed control system closed loop transfer function (w1/w1ref) becomes greater toward the negative side than a value obtained by multiplying a resonant frequency by a negative sign, and a control gain of the output side control device 6 is set such that the real part of a pole of a shaft torque control system closed loop transfer function (Tk1/Tk1ref) becomes smaller toward the negative side than the real part of the pole of speed control system closed loop transfer function.
