Abstract
This paper reports the finding a new fourscroll chaotic system with four nonlinearities. The proposed system is a new addition to existing multiscroll chaotic systems in the literature. Lyapunov exponents of the new chaotic system are studied for verifying chaos properties and phase portraits of the new system via MATLAB are unveiled. As the new fourscroll chaotic system is shown to have three unstable equilibrium points, it has a selfexcited chaotic attractor. An electronic circuit simulation of the new fourscroll chaotic system is shown using MultiSIM to check the feasibility of the fourscroll chaotic model.
