These works stem from research projects conducted during my Masterβs studies. They primarily focus on estimationj methods for a class of Nonlinear Parameter-Varying systems, with illustrative applications to semi-active automotive suspension systems. I refer to these systems as linear-like, as despite their having some nonlinearities, the proposed techniques rely largely on linear system properties.Β
