摘要

研究带有未知参数和外界扰动的异结构混沌系统有限时间同步,采用自适应控制方法实现系统的有限时间同步,引入虚拟未知参数有效地避免控制器和参数更新率中出现系统未知参数问题。通过数值仿真验证了该方法的有效性。
        The finite-time synchronization of two different chaotic systems with unknown parameters and external disturbances was studied. The adaptive control method was used to realize the finite-time synchronization of the system. Virtual unknown parameters were introduced in order to avoid the unknown parameters from appearing in the controllers and parameters update rate. Numerical simulations verified the effectiveness of the method.
