Identification is a relevant topic for everyone that is working with analysis of experimental data and mathematical modeling. The topics of identification include measurement collection, signal conditioning, model selection, parameter estimation, and mathematical modeling. The course primarily covers physical models and dynamical models represented as differential equations, transfer functions, and difference equations. Identification is important in control, where mathematical models play an important role in decision-making, prediction, control, simulation, and optimization. Many control design methods assume the existence of transfer functions that describe the controlled process. The derivation of these transfer functions is one of the tasks of identification.
