— In this paper, the authors investigate the problem of designing an observer for Lipschitz nonlinear systems with discrete time measurements (continuous-discrete time systems). The result is based on reachability analysis to synthesize an upper approximation of a reachable set. When this approximation is given in terms of a convex combination of linear(More)
Given a global nonlinear state feedback which stabilizes globally an equilibrium, the aim of this paper is to modify the local behavior of the trajectories in order to get local optimality with respect to a given quadratic cost. A sufficient condition is given in terms of Linear Matrix Inequalities (LMI) to design a locally optimal and globally stabilizing(More)
— This paper investigates the problem of control design for an Organic Rankine Cycle (ORC) for Waste Heat Recovering (WHR). Based on a moving boundary heat exchanger model derived from energy and mass conservation principles, an implicit model, control-oriented and experimentally validated, is presented. Then, a first controller which consists on a(More)
—This technical note concerns observer design for Lipschitz nonlinear systems with sampled output. Using reach-ability analysis, an upper approximation of the attainable set is given. When this approximation is formulated in terms of a convex combination of linear mappings, a sufficient condition is given in terms of linear matrix inequalities (LMIs) which(More)
