A Disturbance-Observer-Based Sliding Mode Control for the Robust Synchronization of Uncertain Delayed Chaotic Systems: Application to Data Security

This article proposes a disturbance observer-based Sliding Mode Control (SMC) approach for the robust synchronization of uncertain delayed chaotic systems. is done by, first, examining and analyzing electronic behavior master slave Sprott Then, synthesizing sliding mode control technique using newly proposed surface that encompasses error between slave. The external disturbances affecting system were estimated observer. proof semi-globally bounded was established Lyapunov stability theory. efficiency first assessed simulation study, then, experimentally validated on data security system. obtained results confirmed properties in presence time-delays disturbances. experimental validation also its ability to ensure secure transfer data.
