摘　　要：利用电子线路实验实现了用正比于系统变量周期脉冲扰动法 (PP SV)控制超混沌 ,只用单一输出信号作为反馈信号 ,改变原来只对系统变量进行自身替换的方式 ,将反馈信号加到系统的其他变量上 .将这种改进的方式用于一个超混沌电路中 ,得到了很好的控制效果 .数值模拟结果与实验结果基本符合 .The control of hyperchaos in the circuit by means of proportional periodic pulse perturbation to the system variables (PP-SV) has been realized. By using a single output signal of the system as the feedback variable, we and not only replace the system variable by itself, but also add the feedback signal to other system variables, and thus achieve good control results. The results of numerical simulation are in good agreemend with the experimental data.
