Summary:
Many switched circuits are made of linear components switched by a simple logic unit. In this paper, we use a generic planar Piecewise Affine Hybrid System (PWAHS) to model this kind of circuits. Usually, simulations are run by analytical methods (adapted to a specific simple model) or by numerical simulations that can miss some events occurrences. We propose a generic planar method to simulate PWAHSs with periodic and state dependent events. Using analytical expression, our approach can reach arbitrate accuracy in event detections without any loss. As a result, we have implemented our method in a Scilab toolbox.
