Learning outcomes

The aim of this course is to provide competencies and methodologies for the mathematical modelling and simulation of dynamic systems. Both state-space and energy-based approaches are treated over various physical domains: electrical, mechanical, electromechanical, hydraulic, thermal. Part of the course concerns the simulation of dynamic systems with the package MATLAB/Simulink.

Course contents

Systems and models. Evolution of mathematical models in science and technology. Mathematical models as approximation of reality: concept of competent model. Simulation. Modelling and identification. Classification of models. State-space models: linear, non linear, time-invariant. Equilibrium and stability. Linearization.  Lyapunov criteria. Constructing state-space models of dynamic systems belonging to different physical domains: electrical, mechanical, electromechanical, hydraulic, thermal. A unifying approach in dynamic system modelling: effort and flow variables. Engineering multiports and power ports. Bond graph modelling of dynamic systems. Numerical solution of differential equations: Euler's method, implicit and explicit Runge-Kutta methods, predictor-corrector methods, multistep methods. Computer simulation of dynamic systems with the package MATLAB/Simulink.
