MATLAB as a tool for modelling and simulation of the nonlinear system

Abstract

This contribution describe the process that usually precedes the design of the controller - a modelling and a simulation of the observed technological system. Two types of models, physical and abstract, are discussed here. While physical model is usually small or simplified representation of the originally bigger system, the abstract (mathematical) model is description of the system in the form of linear or nonlinear ordinary or partial differential equations. Simulation of the mathematical model then means numerical solution of these equations using some mathematical software. The proposed modeling and simulation procedure is then applied on the real model of the water tank. The mathematical model was then derived and then subjected to the simulation of the steady-state and dynamic analysis. © 2019, Springer International Publishing AG, part of Springer Nature.
