Chapter 2 Dynamic ModelsDynamic Model:mathematical description of the processHow to model a dynamic system?Fit P iil (iilidescription of the process. Typically, a set of differential equations. First Principal (principals in physics)Experimental methodsThese equations can be Nonlinear Time Varying and Infinite Dimensional.Mechanical Systems: Various forms of Newton’s LawLinear motion: F=maIn this course, we consider a special class of approximations: Linear Time Invariant (LTI) processesRotational Motion: Electric Circuits:Kirchhoff’s current law (KCL)TIθ=&&processes. Models can be given in other forms:Transfer functions descriptions and graphical forms etcKirchhoff s current law (KCL)Kirchhoff’s voltage law (KVL)and graphical forms, etc
