Zusammenfassung:	There is provided an apparatus for controlling a permanent magnet synchronous motor in a permanent magnet synchronous motor system. The apparatus comprises a disturbance observation circuit unit configured to estimate concentrated disturbance of the permanent magnet synchronous motor using a nonlinear observation gain function; and a sliding mode controller configured to control the permanent magnet synchronous motor by reflecting the estimated concentrated disturbance in a position-current single-loop control in which back-stepping control and sliding mode control are integrated.
