Resumo: Switched affine systems are a subset of hybrid systems having remarkable characteristics. Their dynamic equations present a discontinuous affine dependence on the state and no other input than the switching signal, which makes them suitable for either locally approximating complex nonlinear switched systems or modeling several devices in power electronics, e.g., DC-DC converters and Voltage Source Inverters. Generally, the origin is not a common equilibrium point and other types of attractors, such as forward invariant sets and limit cycles, become paramount for the stability analysis, in special under a limited-frequency switching. This webinar covers novel and classic aspects of stability and stabilizability analysis of this class of systems and presents motivations for employing switched systems theory for controlling real-world switching devices.
