Apparatus and detecting back electro-motive force in sensorless motor


There are provided an apparatus and a method for detecting back electro-motive force (emf) in a motor. The apparatus includes: a mode selecting unit selecting between an amplification mode and a bypass mode when power is on; a back emf amplifying unit amplifying a back emf voltage from the motor during an initial driving period if the amplification mode is selected by the mode selecting unit, and allowing the back emf voltage to bypass it after the initial driving period if the bypass mode is selected by the mode selecting unit; and a zero-crossing detecting unit detecting a zero-crossing of an output signal from the back emf amplifying unit, wherein the back emf amplifying unit amplifies the back emf voltage to a level detectable by the zero-crossing unit or higher..

Position control identifying low-frequency disturbance


A position control apparatus is provided that can perform accurate nonlinear compensation control immediately after the apparatus is activated. At a time of acceleration, a signal amplification ratio is calculated and designated for each signal vector element based on information related to acceleration/deceleration at a starting time and the structure of a signal vector that is determined for a target plant, and as a result, a signal vector for which the strength of linear independence is increased is generated.
