Abstract
An input-side control device includes: a feedback controller 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 that generates a second control input signal by multiplying the signal difference by k·Jdy/Jset; and a low-pass filter that generates a torque command signal Tr from a signal obtained by combining the outputs of the controllers and attenuating components at a higher frequency than a cut-off frequency fc set in the vicinity of the resonant frequency.
