Abstract
An electric inertia control deviceA simulates the behavior of an inertial body having a predetermined set moment of inertia Jby means of a dynamometer, and is provided with: an inertia compensatorA which generates a torque signal by multiplying a signal obtained by subtracting a shaft torque detection signal Tfrom a higher-level command torque signal T* by the ratio of a moment of inertia Jof the dynamometer to the set moment of inertia J, and generates an inertia compensation torque signal Tby summing the torque signal and the shaft torque detection signal J; and a resonance suppression control circuitA which uses the inertia compensation torque signal Tand the shaft torque detection signal Tto generate a torque current command signal Tin such a way as to suppress resonance in a mechanical system including a test piece and the dynamometer.
