Nonlinear control of a coupled PDE/ODE system modeling a switched power converter with a transmission line
Résumé
We consider an infinite dimensional system modelling a boost converter connected to a load via a transmission line. The governing equations form a system coupling the telegraph partial differential equation with the ordinary differential equations model-ing the converter. The coupling is given by the boundary conditions and the nonlinear controller we introduce. We design a nonlinear saturating control law using a Lya-punov function for the averaged model of the system. The main results give the well-posedness and stability properties of the obtained closed loop system.
