In the previous article, we had learned about Kalman filter. As Kalman filter assumes linear system but finds greatest applications in non-linear systems. Kalman filter assumes an approximate solution, describe the deviations from the reference by linear equations. Kalman filter has

## Kalman Filter | Algorithm & Applications

The Kalman filter is a recursive state space model based estimation algorithm. In other words, it is an optimal recursive data processing algorithm. Kalman filter is also called as the Predictor-Corrector algorithm. This filter is named after Rudolph E. Kalman,

## Parametric and Non-Parametric Models

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

## Types of Identification

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 the relation between input u(t) and

## Identification Definition & Model Types

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

## Procedure for Identification

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

## Difference between Theoretical Modelling and Identification
