提出了一种绝对值函数反馈控制的同步方案，通过将状态变量的误差信号进行绝对值处理后，引入到受控系统中，实现全状态混合投影同步。以两个初始值不同的光滑变形蔡氏电路系统为例，基于Multisim 11电路仿真软件，设计了相应的同步电路图，研究了两个系统在选取相同和不同比例因子情况下的全状态变量投影同步。同时搭建实际硬件电路，对比数值仿真结果，验证所提方案的有效性。

In this paper,a control strategy including absolute function for the chaos synchronization is presented. The state variable error signals are inserted into the controlled system to achieve full-state hybrid projective synchronization of chaotic systems. Based on the software NI Multisim 11,the synchronization circuit of smooth modified Chua's circuit with different initial conditions are designed and implemented to realize projective synchronization for the same and different scale factors. Experimental observations are in agreement with numerical simulations,which verify the effectiveness of the scheme.
