Abstract: This research work investigates anti-synchronisation of identical chaotic systems via a novel sliding control method. Explicitly, a general result is derived for the anti-synchronisation of identical chaotic systems using the novel sliding control method. This paper also announces a novel 3D chaotic system with four quadratic nonlinearities. The Lyapunov exponents of the novel chaotic system are obtained as L1 = 3.7828, L2 = 0 and L3 = −18.7651 while the Kaplan-Yorke dimension of the novel chaotic system is obtained as DKY = 2.2016. The qualitative properties of the novel chaotic system are discussed in detail. As an application of the general control result, a sliding mode controller is derived for achieving anti-synchronisation of the identical novel chaotic systems for all initial conditions. Numerical simulations have been shown to depict the phase portraits of the novel chaotic system and the sliding mode controller design for the anti-synchronisation of identical novel chaotic systems.
