Motor servo-system controller having comparison of detected current with model current integrations

摘要

To set the magnitude of the inertia of a motor and mechanical system or set gains suitable for the magnitude of vibrations of the motor and the mechanical system, the magnitude of a load inertia is identified in accordance with the time-integrated value of motor current to determine the gains of a feedback control loop in accordance with the identified value before executing feedback control in accordance with the determined gains.
