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

Semi-active suspension control using "fast" model predictive control

Proceedings of the 2005, American Control Conference, 2005., 2005
The problem considered in this paper is the design and the analysis of a control strategy, for semi-active suspensions in road vehicles, based on model predictive control (MPC) techniques. The computed control law, using predictive techniques aims to optimize, the suspension performance, by minimizing a quadratic cost function while ensuring that the ...

A new concept of semi-active suspension with controllable damper and spring

2009 European Control Conference (ECC), 2009
The problem considered in this paper is the design and analysis of implementable architectures for semi-active suspensions characterized by a regulation of both damping and stiffness coefficients. The first contribution of this paper is the introduction of a suspension architecture that makes possible the emulation of the behavior of an ideal ...

MIX-1-SENSOR: A CONTROL STRATEGY FOR SEMI-ACTIVE SUSPENSION.

IFAC Proceedings Volumes, 2007
Abstract The topic of this paper is the design and analysis of a control strategy for semi-active suspensions in road vehicles. Currently used closed-loop control strategies (like the Sky-Hook damping) require at least two sensors for each suspension. In this paper a simple but very innovative algorithm is proposed, capable of providing quasi-optimal

Observer Design for Semi-Active Suspension Control

Vehicle System Dynamics, 1999
This paper presents an observer for automotive semi-active suspension control. Automotive suspensions are disturbance affected dynamic systems and semi-active suspensions can be represented as a bilinear model. An observer for semi-active suspensions is formulated such that the estimation error is independent of unknown external disturbance.

Control Strategies for Semi-Active Lorry Suspensions

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 1996
The optimum level of passive damping for minimizing the root mean square (r.m.s.) dynamic tyre force and r.m.s. body acceleration of a heavy vehicle is determined by testing a damper in a ‘hardware-in-the-loop’ (HiL) test rig. Two different control strategies [‘modified skyhook damping’ (MSD), and linear optimal control with full state feedback (FSF ...

OPTIMAL SKYHOOK CONTROL FOR SEMI-ACTIVE SUSPENSIONS

IFAC Proceedings Volumes, 2006
In this paper we derive an optimal skyhook control based on industrial specification, coupled with a reduced order observer when only one sensor is to be used. We emphasize the simplicity of this method that can easily be implemented in a real-time embedded application.

Fuzzy control of semi-active automotive suspensions

2009 International Conference on Mechatronics and Automation, 2009
This paper presents a new fuzzy controller for semi-active vehicle suspension systems, which has a significantly fewer number of rules in comparison to existing fuzzy controllers. The proposed fuzzy controller has only nine fuzzy rules, whose performance is equivalent to the existing fuzzy controller with 49 fuzzy rules.

Control of Mechatronic Semi-Active Vehicle Suspensions

IFAC Proceedings Volumes, 2002
Abstract After discussing the various principles of suspensions with variable dampers and springs mathematical models of these systems are derived. It is shown how the unknown parameters can be obtained experimentally by parameter estimation. Then two feedback principles are derived for controlling the suspension.
