Identificación de Modelos LPV para el Control de Sistemas No Lineales

In this paper we suggest a methodology for the identification of linear parameter time varying models (LPV), based on a previous local identification at some operating points, which presents a high degree of flexibility in adaptations to non-linear processes. These LPV models are characterised by containing within their dynamic trajectories those ones of the original non-linear system, and they will be defined by a linear fractional dependence with respect to the time varying parameters. When the LPV model has been identified, it is possible to design, in turn, a linear controller with parameters that vary in time in order to control the non-linear system. This identification and control methodology will then be applied to a non-linear turbocharged diesel engine.
