ABSTRACT:
A position controller includes a position control part that calculates a speed command on the basis of a difference between a position command and a rotation position of a motor, a PI control part that calculates a torque command on the basis of a speed difference between the speed command and a feedback speed, an observer that generates the feedback speed on the basis of the torque command and a rotation speed of the motor, a phase lead compensator that generates a phase lead compensation signal of the torque command on the basis of the speed command, and an adder that generates a new torque command by adding the phase lead compensation signal of the torque command to the torque command.
