Abstract

This PhD research project aims to develop new conditions of stability analysis and designof controllers and filters for dynamical systems represented by linear mathematical models with parametric uncertainties, time-invariant and time-varying, non-linearities such as saturation, dead zone, etc., focusing in particular on switched systems. In the context of control and filtering, the robust and scheduled gain (i.e., parameter-dependent) cases are considered, possibly with structural constraints (suitable to handle decentralization and output-feedback) and, as performance criteria, the H-2 and H-infinity norms. Continuous- and discrete-time models are investigated, as well as sampled data, by means of Lyapunov functions with polynomial dependence on the parameters that produce Linear Matrix Inequality (LMI) conditions. The results are illustrated by applications in mathematical models for engineering systems. (AU)
