    摘要: 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.

    摘要: A test piece characteristic estimation method includes estimating a moment of inertia of a test piece. A first transfer function G1 from a torque current command for a dynamometer to output from a shaft torque sensor is measured by vibrationally operating the dynamometer. A second transfer function G2 from the torque current command to the output of a dynamo rotation speed sensor is measured by vibrationally operating the dynamometer. A real part and an imaginary part of a ratio obtained by dividing the second transfer function G2 by the first transfer function G1 at a prescribed measurement frequency ωk are calculated. A moment of inertia Jeg and a rotational friction Ceg are estimated by using the real part and the imaginary part of the ratio.
