Title:
ELECTRIC INERTIA CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/095506
Kind Code:
A1
Abstract:
According to the present invention, an input-side dynamometer control device is provided with an inertia compensator, a resonance suppression controller 53, a set value acquisition unit 58 for acquiring set values Jset, Jtgt. The resonance suppression controller 53 is provided with: a plurality of resonance suppression control modules 541-546 that generate input-side torque current command signals T1 on the basis of an inertia compensation torque signal Tref and an input-side shaft torque detection signal T12 so as to suppress resonance and that have respectively different input/output characteristics; and a selector 55 that selects one of the resonance suppression control modules 541-546 on the basis of the set values Jset, Jtgt. The inertia compensation torque signal Tref and the input-side shaft torque detection signal T12 are inputted to one of the resonance suppression control modules selected by the selector 55, and the input-side torque current command signal generated by the selected resonance suppression control module is inputted to an inverter.
