Introduction
In this Project Our aim is to identify An Control of Non linear chaotic system
For that we use Matlab Software and simulate code for different chaotic system
We have use Chua’s circuit and Volta’s circuit
we have do different simulation with help of the circuit
What is Nonlinear & Chaotic system
A system Which does not satisfy Super Position Theorem are called Non linear system
We Know that it is difficult to control and Identify non linear system
Nonlinear systems are very interesting to engineers and physicists because most real physical systems are inherently nonlinear in nature
Concept of Chua’s Circuit
Chua’s circuit is a simple electronic circuit that exhibits nonlinear dynamical phenomena such as bifurcation and chaos
In order to exhibit chaos, an autonomous electronic circuit must satisfy some essential criteria which are necessary conditions for the appearance of chaos
the circuit must contain at least three energy-storage elements at least one nonlinear element and at least one locally active resistor
Simulation results of chua’s circuit
In simulation we have take three values for find out a chaotic system
In the first case we have take same order of the system
In the second case we have take different order of the system
In the third case we have take two order of the system same and third order is different
Order of system=q1,q2,q3
Identification
In identification of circuit we use neural network anfis and system identification tool box to find out our circuit’s compatibility with ideal circuits
In neural network we use input and out put data of our chua’s circuit to train our input z(k) and out put y3(k) graph.
After doing this it will give the error graph between z(k) and y3(k)
Simulation results of volta’s circuit
In simulation we have take three values for find out a chaotic system
In the first case we have take same order of the system
In the second case we have take different order of the system
In the third case we have take two order of the system same and third order is different
Order of system=q1,q2,q3
