摘　　要：Multi-switching synchronizatio of multiple different orders unknown chaotisystems confines hacking in the digital transmission process.Similarly,the suppression of undesirable chattering increases synchronization performance.This paper proposes a new robust synchronization contro technique and discusses the MSS of multiple different orders UC systems.This controller accomplishe quick convergence reduces the transient oscillations,an the rate of convergence decreases in the vicinity of the origin that causes the suppression of chattering.Analysis based on the Lyapunov direct method assures this convergence behavior with any positive values of the feedback gains.This work also provides parameters updated law that estimates the true values of unknown parameters.Numerical examples of five UC systems different orders are simulated.The computer based graphical results validate the efficiency and performance of the proposed RASC technique and the synchronization strategy when compare to peer works.In the simulation,the proposed synchronization strategy successfully recovers an encrypted received image on a communication channel.The article suggests some future research problems to extend the use of the proposed work.
