摘要： 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.

摘要： A method and apparatus for detecting a free fall of an electronic device. The method includes: sensing a falling acceleration of the electronic device using an acceleration sensor; determining whether the sensed falling acceleration is less than a predetermined threshold; when the sensed falling acceleration is less than the predetermined threshold, determining whether the falling acceleration is a statistical constant, which has a statistical significance, and is maintained for a predetermined time; and when the falling acceleration is a statistical constant and maintained for a predetermined time, determining that the electronic device falls freely. Accordingly, it is possible to exactly detect a free fall of an electronic device, irrespective of an error of the acceleration of gravity generated when a falling acceleration of the electronic device is measured, due to ambient conditions, e.g., a temperature change and a rotation acceleration generated when the electronic device rotates.
