摘要：
This paper aims to investigate the predefined-time synchronization analysis for two chaotic systems with different dimensions. Firstly, based on the definition of predefined-time stability, we propose a new con-trol protocol that can realize the synchronization of two chaotic systems with different dimensions in predefined-time. Secondly, by using adaptive control the predefined-time synchronization analysis of two different dimensional chaotic systems in the presence of parameter uncertainties is also taken into ac-count. Our results improve and extend some recent works. Finally, the efficacy of the obtained results is proven by numerical simulations. (c) 2021 Elsevier Ltd. All rights reserved.
