“…The chaotic system is very important in modeling and application of many phenomena and actual systems in various fields, such as a ship's roll motion under symmetrical longitudinal waves [1], magnet levitated over a superconductor [2], suspension control for rail vehicle system [3], successive half sine speed bumps with a nonlinear air suspension system [4], wireless mobile robot [5], visible light communication systems [6], epilepsy and epileptic seizure detection [7], mesoscale-coupled memristor Bi-neuronal Morris-Lecar network [8], System of wind turbines with a permanent magnet synchronized generator (PMSG) [9], FPGA implementation and its image encryption [ [10]. Recently, research on financial risk (FR) system's chaotic behavior has also become a very important domain in both micro and macroeconomics.…”

This study presents the findings of a new financial risk system (FRS) with one absolute function and two quadratic nonlinearities. The rich dynamic behaviors of the new financial risk system are discussed analytically and numerically through stability analysis, phase portrait, bifurcation diagram, Lyapunov exponent, multistability and coexisting attractors. In addition, a new financial risk system with two quadratic nonlinear-ities and one absolute function shows multistability and coexistence of chaotic attractors. Using adaptive feedback control, we established a new control law for fully synchronising the proposed chaotic financial systems with itself. To conclude, some numerical simulation was presented using MATLAB to illustrate the efficiency of the designed method.
