This article presents the novel fractional-order Genesio–Tesi system, along with discussions of its boundedness, stability of the equilibrium points, Lyapunov stability, uniqueness of the solution and bifurcation. The efficient predictor–corrector approach is employed to quantitatively analyse the Genesio–Tesi system in fractional order. The findings enable conceptualisation and visualisation of the presented novel fractional-order Genesio–Tesi systems. The modified systems are proposed for future study on chaos control and applying the same for secure communication. Bifurcation analysis is carried out to see the variation in the system's behaviour from stability to chaos. The results of the bifurcation analysis support the results obtained for the stability of the equilibrium points. The system behaves chaotically since all the equilibrium points are unstable. The findings demonstrate a torus attractor for some of the suggested systems and a chaotic attractor for some of the novel fractional-order Genesio–Tesi systems. The system's torus attractor changes into a steady state when the order is reduced from integer to fractional. Changing the parameter values for one of the modified systems also shifts the system's behaviour, with the point attractor replacing the torus attractor. The point attractor of one of the systems changes into a steady character when the system's order is reduced from integer to fractional. The behaviour for one modified system is the same for fractional and integer orders. This discovery paves the way for the future study of the modified Genesio–Tesi system. This article gives a new direction to utilise these proposed Genesio–Tesi systems and study them extensively. The chaotic behaviour of the modified system can be used for secure communication. The synchronisation and chaos control of the modified system is recommended. [ABSTRACT FROM AUTHOR]
