A mathematical model of a dynamic system is defined as a set of equations that represents the dynamics of the system accurately, or at least fairly well. For a system of planets the state is simply the positions and the velocities of the planets. Differential equation model is a time domain mathematical model of control systems. Control systemssystem modeling wikibooks, open books. Note that a mathematical model is not unique to a given system. Mathematical modeling of a control system is the process of drawing the block diagrams for these types of systems in order to determine their performance and transfer functions.
