Disturbance and Uncertainty Rejection-Based on Fixed-Time Sliding-Mode Control for the Secure Communication of Chaotic Systems

This study provides a new development regarding uncertainty and disturbance estimation (UDE) based on fixed-time sliding mode control (FTSMC) for the secure communication of electronic circuits in chaos-based system. Takagi-Sugeno (T-S) fuzzy systems were used to remodel chaotic with aim softening design synchronization The master slave system maintained formats. originality proposed estimator is condition associated first derivative these values being free. stability was proven by using Lyapunov condition. states encryption decryption, respectively. Finally, correction theories verified MATLAB simulations, simulation OrCAD capture software, experiments involving circuit communication.
