Damping force control of a vehicle MR damper using a Preisach hysteretic compensator

Abstract

This paper presents damping force control performances of a magnetorheological (MR) damper via a new control strategy considering hysteretic behavior of the field-dependent damping force. In order to achieve this goal, a commercial MR damper, Delphi Magneride™ which is applicable to a high-class passenger vehicle is adopted and its field-dependent damping force is experimentally evaluated. The MR damper has two types of damping force hysteretic behavior. The first is velocity-dependent hysteresis and the other is field-dependent hysteresis. Since the magnetic field is directly connected with control input, the field-dependent hysteresis largely affects the control performances of the MR damper system. To consider the field-dependent hysteretic behavior of the MR damper, a Preisach hysteresis model is established and its first-order descending (FOD) curves are experimentally identified. Subsequently, a feedforward hysteretic compensator associated with the biviscous model and inverse Bingham model is formulated to achieve the desired damping force. The control algorithm is experimentally implemented and damping force controllability for sinusoidal and arbitrary trajectories is evaluated in terms of accuracy and input magnitude. In addition, vibration control performances of the MR suspension system are experimentally evaluated with a quarter-vehicle test facility.

Amplitude and frequency independent cable damping of Sutong Bridge and Russky Bridge by magnetorheological dampers

“…If c mr ≠ 0 , the friction force must also be controlled to avoid the aforementioned drawbacks. In addition to this, the control approach must fulfil the following requirements:The resulting MR damper force must also generate frequency independent cable damping because the most often occurring vibration modes are unknown because of the unknown wind loading.Collocated control is targeted to minimise the number of sensors and the complexity of the control system and thereby enhance its robustness .The desired control force must not contain too high frequency components, which cannot be tracked by MR dampers because of their limited bandwidth .The desired control force must be realised with acceptable small force tracking error by a model‐based feed forward only that estimates the MR damper current without force feedback to save the costs of a force sensor with amplifier.…”

Performance evaluation of a quarter-vehicle MR suspension system with different tire pressure

“…A semi-active suspension system using magnetorheological (MR) fluid can offer the desired performance in the active mode without requiring large power consumption and expensive hardware. MR fluid, the rheological properties of which can be rapidly changed by applying a magnetic field to the fluid domain, has been used in many devices such as dampers, [3][4][5][6][7][8] valves, [9][10][11][12] engine mounts 13,14 and clutch/brake 15,16 systems.…”

“…On the basis of this work, they extended their research and evaluated control performance of the proposed MR damper via hardware-in-the-loop simulation. 7 Recently, Seong et al 8 evaluate a accurate damping force model and a hysteretic behavior of a commercial MR damper, Delphi Corporation's Magneride TM which is used for high-class passenger vehicles.…”

Control Strategies for Vehicle Suspension System Featuring Magnetorheological (MR) Damper

“…Yu et al, 2009 developed human simulated intelligent control algorithm and successfully applied it to vibration control of vehicle suspension featuring MR dampers. Seong et al, 2009 proposed hysteretic compensator of MR damper. They developed nonlinear Preisach hysteresis model and hysteretic compensator and demonstrated its damping force control performance.…”
