Title:
DYNAMOMETER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/053979
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a dynamometer control device capable of performing a stable inertia-lowering control of an input-side dynamometer. An input-side control device 5 comprises: a feedback controller 51 that generates a first control input signal for eliminating the difference between a model speed signal ωm and a speed detection signal ω by using the signal difference between a higher order torque command signal Tref and an axial torque detection signal Tsh to generate the model speed signal ωm which corresponds to the rotational speed of an inertial body having a set moment of inertia Jset moving under a torque corresponding to the signal difference; a feed-forward controller 55 that generates a second control input signal by multiplying the signal difference by k·Jdy∕Jset; and a low-pass filter 57 that generates a torque command signal Tr from a signal obtained by combining the outputs of the controllers 51 and 52 and attenuating components at a higher frequency than a cut-off frequency fc set in the vicinity of the resonant frequency.
