本文研究了不确定Van der Pol混沌系统的同步问题，并进行了基于规则的模糊逻辑控制器(FLC)的控制。首先寻找主从Van der Pol混沌系统满足Lyapunov稳定性理论的条件，在此基础上建立模糊规则，设计模糊控制器，实现不确定混沌系统的同步。通过不确定Van der Pol混沌系统的两组仿真结果，验证了模糊同步控制方法具有很好的鲁棒性。最后为了进一步验证该方法的有效性，本文在相同条件下，利用反馈控制的方法实现不确定主从Van der Pol混沌系统的同步，然后再将此方法的仿真结果与本文的模糊同步控制方法的仿真结果在稳态误差及同步所需时间这两个方面进行对比分析。分析结果验证了本文同步方法的可行性及有效性。

In this paper the synchronization problem of the uncertain masterslave Van der Pol chaotic system is studied and the design of a rulebased controller is presented.Firstly,we directly make the masterslave Van der Pol chaos system satisfy stability in the Lyapunov sense.Secondly,we construct the fuzzy rules subject to a common Lyapunov function for the synchronization of the masterslave Van der Pol chaos system.Two couples of simulation results show the effectiveness of the proposed method.But in order to further show the effectiveness of the method,under the same conditions,an approach of the synchronization of the uncertain masterslave Van der Pol chaotic system using feedback control is proposed,which compares the steadystate error and the time of synchronization with the proposed method.The results show the effectiveness of the proposed method.
