Mechatronic semi-active and active vehicle suspensions

Control Engineering Practice, 2004
After discussing various principles of suspensions with variable dampers and springs as well as active components, mathematical models of these systems are derived. It is shown how the unknown parameters can be obtained experimentally through parameter estimation by using body accelerometers, wheel accelerometers, and suspension deflection sensors in ...

Batch Reinforcement Learning for semi-active suspension control

2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC), 2009
The object of this work is the design of a control strategy for semi-active suspension. In particular this paper explores the application of Batch Reinforcement Learning (BRL) to the design problem of optimal comfort oriented semiactive suspension. BRL is an artificial intelligence technique able to provide an approximate solution of optimal control ...

Modeling and Simulation of Semi-Active Suspension for Vehicle

2013
In order to shorten the development cycle of semi-active suspension, a batch processing modeling method is studied. 1/4 of the semi-active suspension model is constructed based on AMESim software in this modeling method. Through changing model’s parameters, the simulation results are compared and the system’s performance is analyzed.

Semi-Active Suspension Laboratory System

Solid State Phenomena, 2009
The paper describes the semi-active suspension laboratory system (SAS), built to demonstrate and test a number of control algorithms. The heart of the system is the automotive engineering damper with the restoring force controlled by magnetic field.

Hybrid active and semi-active seat suspension

2019
In this chapter, a hybrid active and semi-active seat suspension for heavy-duty vehicles is experimentally investigated to fill the performance gap between the two kinds of seat suspensions. An active actuator with low continuous force output, which is insufficient for an active seat suspension system, is applied together with a semi-active MRF damper.

Simulation and Evaluation of Semi-Active Suspensions

SAE Technical Paper Series, 1994
<div class="htmlview paragraph">A simulation of the vertical response of a nonlinear 1/4 car model consisting of a sprung and an unsprung mass was developed. It is being used for preliminary evaluation of various suspension configurations and control algorithms.

Semi-active suspensions with adaptive capability

Journal of Sound and Vibration, 1995
This paper deals with the synthesis of control laws for a 2-DOF model of a vehicle with a semi-active suspension. The suspension system consists of a continuously variable damper and a spring that can vary the suspension stiffness among three different levels.

Development of Semi-Active Truck Suspension

IFAC Proceedings Volumes, 1997
Abstract Within the EC project Copernicus SADTS (Semi-Active Damping of Truck’s Suspension and Its Influence on Driver and Road Loads) the semi-active suspension for Liaz truck prototype is being developed. The objective is to decrease the dynamic road-tyre forces in order to reduce the road damage.

Control of Suspensions for Vehicles With Flexible Bodies—Part II: Semi-Active Suspensions

Journal of Dynamic Systems, Measurement, and Control, 1994
Two methods of control of semi-active suspensions that specifically address the problem of structural vibrations of the vehicle body are considered. These control strategies are based on those developed for active suspension systems in Part I of this study and rely on either modifications of suspension control forces that account for body compliance or

Active/semi-active suspension control using magnetorheological actuators

International Journal of Systems Science, 2006
Magnetorheological dampers, which are semi-active devices that use MR fluids to produce controllable forces, can be used as smart actuators to reduce the vibrations of mechanical systems. The advantage of these actuators is the low power input requirements and the high output force they produce.
