Goals

This course in an introduction to modelling, simulation and control of nonlinear systems. It will first provide the students with a mathematical modelling method to cope with complex nonlinear multi-domain (i.e. multiphysics or mechatronics) systems from macroscopic physics. The underlying structure of the derived models allows automated generation and simulation of the associated dynamical equations. It is therefore used by many non profit or commercial simulation softwares (AMEsim, 20-sim, Simscape for Simulink, Modelica/Dymola, …). Basic simulation and analysis principles behind these softwares will be explained. Once formal nonlinear models are obtained, nonlinear analysis and control design model-based tools may be used for the estimation and control of the considered plants. Among the fundamental concepts which are of great practical importance for this are Lyapunov stability and passivity analysis. They will be presented with details and then further applied in nonlinear feedback control design, either for regulation or tracking, using output feedback or dedicated observers. The students will acquire a more advanced knowledge and experience by developing small group projects and paper reviews. Papers and projects topics to be covered will reflect student interest.
