Semi-active suspension control using "fast" model predictive control
Proceedings of the 2005, American Control Conference, 2005., 2005The 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), 2009The 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, 2007Abstract 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

Control of Mechatronic Semi-Active Vehicle Suspensions
IFAC Proceedings Volumes, 2002Abstract 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.

Fuzzy control of semi-active automotive suspensions
2009 International Conference on Mechatronics and Automation, 2009This 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.

The Fuzzy Control Method in Semi-Active Suspension
Advanced Materials Research, 2010Based on the analysis of performance of vehicle and its suspension, half vehicle model of five DOF and road model were built and the dynamic equations of half vehicle were derived according to the parameters of a commercial vehicle. In addition, a novel fuzzy logic control system based on semi-active suspension was introduced to achieve the optimal ...

Sugeno Model Based Control for Semi active Vehicle Suspension
2009In this paper a fuzzy Sugeno rule based controller is used to manage a semi-active suspension of 1/4 vehicle model. Our semi-active suspensions have the characteristic to change the damping constant in order to reduce vertical oscillation of the vehicle, to restrain the shell vehicle acceleration and consequently to be more comfortable for passengers ...

Observer Design for Semi-Active Suspension Control
Vehicle System Dynamics, 1999This 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.

H ∞ Control of Automotive Semi-Active Suspensions
IFAC Proceedings Volumes, 2004Abstract This paper deals with the control of semi-active automotive suspensions using H∞ state-space optimization techniques. After the derivation of two standard models of the system, quarter car and half car model, three H∞ controllers are developed in the fully active case and then adapted to the non-linear real system using a sort of clipped ...
