Title:
TESTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/004640
Kind Code:
A1
Abstract:
An electric inertia control device 6 of this testing system generates a torque current command signal in such a way that a dynamometer behaves as an inertial body having a prescribed set inertia Jset. The electric inertia control device 6 comprises: a target speed setting unit 60 for generating a target speed signal on the basis of a shaft torque detection signal and the set inertia; a speed controller 63 for generating a feedback input signal on the basis of a difference signal between the target speed signal and a speed detection signal; and a feed-forward controller 65 for generating a feed-forward input signal on the basis of the shaft torque detection signal. The feed-forward controller 65 generates the feed-forward input signal by combining the shaft torque detection signal, multiplied by a first feed-forward gain Kff, and an integrated value of the shaft torque detection signal, multiplied by a second feed-forward gain Kfi.
