A Review on Model and Control of Electromagnetic Active Engine Mounts

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.

Foundation forces caused by dynamic air gap torques of converter driven induction motors influenced by active vibration control: a theoretical analysis

“…Now the Laplace transformed output vector Y(s) can be derived by inserting Eqs. ( 19) and ( 21) into (18), with the unit-matrices I 39 ∈ R 39×39 and I 26 ∈ R 26×26 :…”

“…Due to the flexibility of the foundation, critical speeds may occur now in the operational speed range and off-speed ranges have to be accepted. The idea is now to use active vibration control, which is nowadays more and more implemented in many different technical B Ulrich Werner ulrich.werner@th-nuernberg.de 1 Nuremberg Tech, Georg Simon Ohm University of Applied Sciences Nuremberg, 90489 Nuremberg, Germany applications [8][9][10][11][12][13][14][15][16][17][18]. The main goal of this concept here is to prevent off-speed ranges, by active vibration control.…”

“…Sohn et al described in [17] their experimental research regarding an electromagnetic actuator, for active vibration control. Zhang et al showed in [18] the current status and development of electromagnetic active engine mounts. The goal of this paper now is to point out the use of active motor foot mounts for large induction motors (power rating > 1 MW).…”

Principle and Control of Active Engine Mount Based on Magnetostrictive Actuator

“…Moreover, it is difficult for passive mounts to meet the requirements of vibration isolation and relative position control performance in the wide frequency band simultaneously [2]. Active mounts can achieve better vibration isolation and relative displacement control performance in a broader frequency bandwidth via active force [3][4][5]. In the research of active mounting systems, the actuators and control methods that directly affect system performance have received extensive attention [6][7][8][9][10][11][12][13][14][15][16][17].…”
