EPS용 IPMSM의 토크리플 저감 최적설계

Abstract

Recent automotive industry, environment-friendly automotive business in accordance with environmental regulations has been actively carried out. But, research has also been continuously carried out for stability and improved ride comfort of the vehicle. As a result, it is possible to replace developed several hydraulic power steering system (HPS) to the electric power steering system (EPS). EPS has an advantage in maintenance and fuel efficiency. The torque ripple reduction of the electric motor is essential to implement the smooth steering feel. In this paper 1/4Fractional Factorial Design (FFD) and the Response Surface Method (RSM) by using, to consider the optimal design aimed at reducing the torque ripple of the electric motor.
