摘要
针对四阶和三阶混沌Colpitts电路系统,利用Active方法对系统的同步进行了研究,实现了不同阶Colpitts电路系统在超高频域内的主从混沌同步。同时对系统在存在内部参数扰动和外部干扰的情况下,分析了控制器的鲁棒性。最后通过数值示例进行仿真,对文中论述进行了强有力的验证。
This paper discusses synchronization of chaotic Colpitts circuit system with two different orders by using active control method, and realizes the master-slave Colpitts circuit synchronization in ultra-high frequency. At the same time, the robustness of controller for perturbation of system parameters and external noise is analyzed. Finally, the verification of the discussed synchronization by numerical simulation is given in this paper.
