System Identification and Parameter Estimation

• What is system identification? A set of methods to obtain a mathematical model of a dynamic system from experimental data. • What is the goal of system identification? The obtained model should on the one hand be compact and on the other hand be adequate for the intended purpose. Such purpose may be the design of a controller for that system. • How is system identification being carried out? In dedicated experiments measurements are carried out on a system. The obtained system response is analysed, e.g. with MATLAB’s system identification toolbox ident.
