In this paper, an overview and a benchmark of some semi-active suspension control strategy performances is proposed. Based on a recent result of the authors, where the optimal semi-active performance trade-off was addressed, here, a complete benchmark to evaluate any controlled semi-active suspensions is proposed, and applied on different control(More)
This paper concerns the study of the optimal performance computation of a semi-active suspension evaluated in terms of comfort and handling performances. To this aim the semi-active suspension system is described as a quartercar model, equipped with a controllable damper, providing an effective representation of the semi-active suspension dynamics. The(More)
In this paper, the problem of comfort and handling improvements of a ground vehicle is treated through the joint control of the suspension and braking systems. Two H∞ gain-scheduled controllers are synthesized to achieve, attitude and yaw performances according to the driving situation, observed through of a simple vehicle monitor. The proposed strategy(More)
In many highly technological engineering fields, the use of dedicated computer-based dynamical system modeling software often leads to large dimensional Linear Time Invariant (LTI) models. These kind of models, composed of a large amount of variables might render drastically inefficient many analysis, control design and optimization techniques. As a matter(More)
To improve safety on commercial cars, a multivariable Global Chassis Controller (GCC) design, involving braking and steering systems is proposed. In case of emergency (e.g. loss of manoeuvrability), the GCC uses the braking system to handle the problem. But, in case of inefficiency of the braking system (e.g. due to low road adherence, large yaw rate error(More)
In this paper, the problem of medium-scale MIMO LTI systems approximation is addressed. The proposed methodology, inspired from recent developments in the model reduction community (i.e. [1], [2], [3]), consists of combining the features of the SVD reduction approach with the tangential interpolation ones. The contributions of the paper are in two folds:(More)
