# Dynamic model of non-linear system

• srinaath
In summary, a dynamic model of a non-linear system is a mathematical representation that allows for the study and prediction of complex systems. It is created by developing equations that consider the non-linear behavior of the system, and is used in various fields to analyze and understand chaotic systems. However, these models have limitations as they are based on simplifications and may not accurately represent real-world systems, and require a significant amount of data and computational power.

i am finding it difficult to get insight about modelling of non linear system (electrical).
my queries are,
consider the system is DC DC converter...
1) I read that to study the dynamics of the system we linearise the non-linear system...why do we want to linearise it?...
2)can some one please explain me the process of linearisation clearly...why do we want to add perturbation to the operating point...

## What is a dynamic model of non-linear system?

A dynamic model of non-linear system is a mathematical representation of a system that exhibits non-linear behavior, meaning that the output does not change in a direct proportion to the input.

## What is the importance of using a dynamic model for non-linear systems?

A dynamic model allows scientists to study and understand complex systems that cannot be accurately described by linear models. It also allows for the prediction of system behavior under various conditions.

## How is a dynamic model of a non-linear system created?

A dynamic model is created by developing a set of equations that describe the relationships between the different components of the system. These equations take into account the non-linear behavior of the system.

## What are some applications of dynamic models of non-linear systems?

Dynamic models are used in a variety of fields, including engineering, economics, biology, and physics, to study and predict the behavior of complex systems. They are particularly useful in understanding and analyzing chaotic systems.

## What are the limitations of dynamic models of non-linear systems?

Dynamic models are based on assumptions and simplifications, so they may not always accurately represent the real-world system. They also require a considerable amount of data and computational power to develop and analyze.
