Observer-Based Finite-Time Modified Projective Synchronization of Multiple Uncertain Chaotic Systems and Applications to Secure Communication Using DNA Encoding

This paper studies an observer-based finite-time scheme for two modified projective synchronization modes, including the synchronization of multiple uncertain chaotic response systems to one drive system and transmission synchronization. First, a finite-time super-twisting observer is designed to estimate the uncertain terms. Then, a finite-time controller is proposed to guarantee the chaos synchronization, and the numerical simulations...
