Abstract
A vehicle system vibration suppression control device is provided for a vehicle system in which a vehicle is driven via an elastic shaft by a motor drive device having a torque control function. The vehicle system vibration suppression control device includes: a section containing an approximate model to which an output torque command is inputted; and a feedback control section. The feedback control section is configured to: employ the approximate model; calculate a motor-accelerating torque component by differentiating a measured speed component of a motor rotational speed; produce a compensation torque component by causing the motor-accelerating torque component to pass through a vibration suppression control filter; and calculate the output torque command by subtracting the compensation torque component from an input torque command. The vibration suppression control filter is expressed by a second order mathematical expression.
