Abstract
To stably control a driving object to approach and contact a pressure object at a low impact, to suppress a vibration generated when the driving object presses the pressure object, and to enable a motor controller to operate based on a simple command, a regression torque controller of the motor controller limits a torque-control velocity command to up to a velocity limit value vlim defined based on a contact velocity between a driving object and a pressure object and outputs the torque-control velocity command, and a velocity controller of the motor controller calculates a torque command so that a motor velocity can follow the torque-control velocity command output from the regression torque controller.
