Pulse Response Based Identification of Low-order Models

In practice, many systems are modeled by first and second order models including a time delay. These low-order models can often be used to describe the most important and characteristic features of a system and be a base for control design. In industry, it is important to have fast, reliable, and easily applicable methods for estimating the parameters in such models. It is well-known that, for practical reasons, many systems can not be excited by an arbitrary input signal. However, a pulse-shaped input signal can most often be used. The aim with this thesis project is to study identification of low-order models based on pulse-shaped input signals
