Overview
The increasing performances of computers and equations solvers have led to a revival in the study of nonlinear systems. The characterization of these systems might be very helpful for engineers and physicists since most of our surrounding natural systems are intrinsically nonlinear.
The thesis will be largely devoted to methods for analysing and modeling nonlinear systems. These methods will be put into practice by modeling a guitar signal chain for real time applications. This chain will be composed of several elements with different nonlinear behaviors.
There is not « one » single method able to model all the nonlinear systems. Therefore several approaches will be proposed to fit each system, including a focus on “black box” methods based on Volterra’s series.
