Abstract
A motor controller to control a motor includes a position controller, a speed controller, a first integrator, and a second integrator. The position controller is configured to generate a speed command based on a position error between a position command and a motor position. The speed controller is configured to generate a torque command to be input to the motor based on a speed error between the speed command and a motor speed. The first integrator is configured to calculate an integral value of the position error to be added to the position error. The second integrator is configured to calculate an integral value of the speed error to be added to the speed error.
