Abstract :
Recently, electric power steering (EPS) systems have attracted much attention due to their advantages such as high fuel efficiency, tunability of steering feel, weight reduction of steering system, environmental friendliness, etc. [1-4]. However, vibroacoustic radiation noise occurs, which is not seen in hydraulic steering systems. The fundamental source of the vibroacoustic noise is considered to be from the electric motor.
