A Study on Adaptive Control Method of Active Control Engine Mount

Abstract

LMS algorithm has been used for an active control. But it can only reduce the first and second firing order in order to reduce booming noise. The authors developed the new method by means of modifying LMS algorithm in order to reduce wide frequency band for comfortable car interior space.
This control method was applied to a vehicle. It was obtained that the seat rail vibration level is reduced in the frequency domain of not only the first firing order but also from 200 to 500Hz.
