## Extended Kalman Filter | Algorithm & Applications

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,

## Servomechanism | Servomotor & Applications

Servomechanism It is a feedback control system in which a controlled variable or the output is a mechanical position or its time derivatives like velocity and acceleration. Servomotors have two main classifications based on servomechanism i.e. 1. DC Servomotors Armature

## Signal Flow Graph

In case of block diagram reduction diagram, there is no standard procedure for reducing the block diagram to evaluate its transfer function. Also, the block diagram reduction technique is tedious and is difficult to choose the rules to be applied

## State Space Representation of a System

The control system analysis fails for multiple-input multiple-output (MIMO) systems and the systems initially not at rest by using transfer function approach. The use of state space approach for the analysis of control systems enables to overcome the shortcomings of the transfer function

## Mechanical Electrical Analogy

Mechanical Electrical Analogy The concept of an analogous system is very useful in practice. Since one type of system may be easier to handle experimentally than other. A given electrical system consisting of resistance, inductance and capacitance may be analogous

## Performance Indices in Control System- ISE,IAE,ITSE,ITAE

When we design a control system for a physical process, one or more parameters are to be selected to give the best performance. For this purpose, a measure known as Performance Indices is used. The usual criteria for performance index are

## Transfer function

Transfer function Definition A transfer function is expressed as the ratio of Laplace transform of output to the Laplace transform of input assuming all initial condition to be zero. Consider a system whose time domain block diagram is where, r(t)

## Control System Basics

Our daily activities are getting automated every day. Control System plays an important role in making our life automated and modernised. A microwave, refrigerator, an air conditioner, a geezer, an automatic iron, are some examples of a control system. Many
