Modified function projective synchronization for two different chaotic systems using adaptive fuzzy nonsingular terminal sliding mode control

This paper proposes an adaptive fuzzy nonsingular terminal sliding mode control (AFNTSMC) scheme for modified function projective synchronization (MFPS) of two different chaotic systems with unknown functions. The proposed scheme combines adaptive fuzzy logic control (AFLC) with fuzzy nonsingular terminal sliding mode control (FNTSMC). The AFLC can estimate the unknown functions. The FNTSMC can reduce chattering phenomenon and convergence time of error states to finite time. The proposed scheme synchronizes these chaotic systems in finite time. The simulation results show the effectiveness of the proposed scheme.
