How to plot Poincare map and Bifurcation diagrams of ferrosonance

I doing research in Ferroresonance. Please help me to learn to plot Poincare map and Bifurcation diagrams of ferrosonance.

Hi, you could help me with your ferroresonance investigation, it would help me a lot because I'm doing a ferroresonance investigation in a transformer bank and I'm going to simulate it.

For bifurcation diagram: Run the system for particular values of the parameter and store the time series. Change one of the parameters (with which you want to study the bifurcation diagram) and simulate the system and store the time series. Do the same thing for all other values of the parameter. Finally, plot the time series vs the parameter which is the bifurcation diagram.

For Poincare section: you have to change ur approach depending on whether the system is autonomous or not. if you give more details I can offer more help.

Sir,

can you give some examples for poincare and bifurcation using matlab or simulink?
