Chua circuit has a wide range of applications, and has received more and more attention of researchers. With the help of the memristor, the researchers constructed a new hyperchaotic system based on Chua circuit. Through the PC control and linear feedback method, the synchronization of two chaotic systems with linear coupling is analyzed. Finally, the validity of the theoretical analysis is verified by numerical simulations.%Chua电路具有广泛的应用价值，受到越来越多的研究者的关注。借助于最新提出的忆阻器电路元件，在Chua系统的基础上构造了一个新的超混沌系统。通过PC控制和线性反馈方法，分析了两个线性耦合的超混沌系统的同步，数值仿真也验证了理论分析的有效性。
