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)
— 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)
— To improve safety on commercial cars, a mul-tivariable 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(More)
In this paper, we propose an overview and a benchmark of the most classic semi-active suspension control laws. Based on a recent result where the optimal semi-active performance trade-off was derived (see Poussot-Vassal et al. (2010)), here, a complete benchmark to evaluate the main semi-active suspension control design methods is proposed. The present(More)
In this paper, a new simple but yet efficient spectral expression of the frequency-limited H2-norm, denoted H2,ω-norm, is introduced. The proposed new formulation requires the computation of the system eigenvalues and eigenvectors only, and provides thus an alternative to the well established Gramian-based approach. The interest of this new formulation is(More)
