Abstract

The isolation of the body from engine vibration is the most challenging and disruptive vibrational problem. Active engine mounts (AEMs), especially electromagnetic AEMs, achieve a significant performance improvement in decreasing the wide frequency band vibration. Increasing research interest is necessary to provide the academic community with a guideline for electromagnetic AEMs. Therefore, the current review aims to comprehensively supplement the review of AEMs. The key reviews of electromagnetic AEMs focus on (1) general considerations of electromagnetic AEMs, (2) models, and (3) control strategies. This paper presents a review of the current status and developmental progress of AEMs. A theoretical model, a finite-element model, and the identification (or experimental modelling) of electromagnetic AEMs during the last 2 decades are then studied. Finally, control strategies, such as classical control, adaptive control, and two degree of freedom (2DOF) control, are discussed and compared. The main purpose of this paper is to meet the needs of researchers and engineers engaged in electromagnetic AEM analysis and control.

Highlights

To meet the requirements of low emissions and low fuel consumption, downsizing, on-demand cylinders (COD), turbochargers, and active fuel management are applied in vehicles [1,2,3,4,5], which results in changes in the engine vibration excitation level and dominant engine order shown in Figures 1(a) and 1(b)
To control the vibrations of the engine-chassis system, Yang [118] proposed a 2DOF control strategy applied on an active engine mount (AEM), which is formed of an H∞ robust feedback controller and a filtered-x least mean squares (FXLMS) feedforward controller
Based on the above review, the difficulties and trends in the research of modelling and controlling AEMs are summarized as follows: (1) Most theoretical models are based on assumptions that are not always consistent with the working conditions of AEMs
