变分数阶不确定混沌系统的有限时间自适应滑模投影同步OA北大核心CSTPCD

The problem of finite-time adaptive sliding mode projective synchronization of variable fractional order uncertain chaotic systems was investigated.Using the properties of variable fractional order calculus,the finite-time convergence principle of variable fractional order was established.The sufficient conditions for finite-time projective synchronization of variable fractional order uncertain chaotic systems were obtained by designing variable fractional order sliding mode surface and adaptive sliding mode controller.The upper bound of projective synchronization time was derived.The simulation results demonstrated the effectiveness and robustness of the controller designed in this paper.
