Adaptive Feed forward Controller Applied for Active Engine Mount System

Arjon Turnip


An active engine mount (AEM) system presented in this paper reduces the transmission of engine vibration to the chassis and the noises in the passenger cabin. To accomplish this goal, an adaptive feed forward control algorithm was employed to the AEM system. This proposed algorithm reduces the response time of control signal and improves the inherent delayed control output in the feedback algorithm by calculating reference signals obtained
from vibration sources. Based on the modeling of AEM system, the simulation result confirms how well the proposed control algorithm performs to reduce the transmitted vibrations from engine to the chassis.
