Computer science description: The problem of identifying linear parameter-varying (LPV) systems, a-priori known to be quadratically stable, is considered in the paper using an input-output model structure. To solve this problem, a novel constrained optimization-based algorithm is proposed which guarantees quadratic stability of the identified model. It is shown that this estimation objective corresponds to a nonconvex optimization problem, defined by a set of polynomial matrix inequalities (PMI), whose optimal solution can be approximated by means of suitable convex semidefinite relaxations. Applicability of such relaxation-based estimation approach in the presence of either stochastic or deterministic bounded noise is discussed. A simulation example is also given to demonstrate the effectiveness of the resulting identification method. publisher: IFAC date: 2012-07 type: Book Section type: PeerReviewed format: application/pdf language: en identifier: http://eprints.imtlucca.it/2448/1/IFAC2012PreprintPiga.pdf identifier: Cerone, Vito and Piga, Dario and Regruto, Diego and Tóth, Roland Input-Output LPV Model identification with guaranteed quadratic stability.
