ABSTRACT:
A hard disk drive is provided. The hard disk drive comprises a plant configured to drive the hard disk drive, a main controller configured to control the plant, and an additional controller connected in parallel with the main controller. A response function in consideration of the plant and the main controller is referred to as a main response function, and a response function in consideration of the plant and the additional controller is referred to as a first response function. The first response function cancels a function value corresponding to a section of the main response function that is associated with disturbance. The response function of the additional controller may be designed using the first response function. The hard disk drive removes a portion of the main response function to minimize the influence of the disturbance.
