In this article, we will learn the basic difference between Parametric and Non-Parametric Models Parametric Models It represents the relation between input and output by means of equations. It contains the finite number of explicit parameters. Model coefficients are not known exactly. White box models are the parametric models. For…

There are 3 types of Identification Deterministic Identification Stochastic Identification Complete system Identification 1. Deterministic Identification The process noise v(t) is absent and measurement noise w(t) is present. We estimate system output y(t). Find relation between input u(t) and output y(t). Measurement of input u(t) and measured output z(t) are…

System The complex interaction between diverse components is called as System. System Variables A state variable is one of the set of variables that are used to describe the mathematical “state” of a dynamical system. State variables are used to represent the states of a general system. example: In electrical circuits,…

In this article we will see the Identification Procedure in detail. The flow chart for Identification is shown below. Flow chart for Identification Procedure The process is divided into 4 steps and are explained as follows: Step-1: Experiment Apply input and observe the effect on output results used to infer a model…

The Difference between Theoretical Modelling and Identification is given in the following table. S.No. Theoretical Modelling Identification 1. Model structure follows from laws of nature. Model structure must be assumed. 2. Modelling of input-output behavior as well as the internal behaviour. Only the input-output behaviour is identified. 3. Model parameters…

The Difference between Online Identification and Offline Identification is given in the following table. S.No. Online Identification Offline Identification 1. Used for control applications. Used for Analysis applications. 2. Model is used for controller design. Model is used for offline simulation of systems. 3. Compact and easy to manipulate model.…
