提出一种利用比例脉冲反馈控制化学混沌的方法 .通过对系统施加正比于变量的脉冲反馈 ,并选取合适的反馈系数和反馈间隔 ,可以获得各种不同的所需的稳定周期轨道 .对Rossler化学混沌系统施于此控制 ,计算机数值模拟结果表明 ,这种控制方法简便有效 。

In this paper an approach to control chaos in chemical system by using proportional pulse feedback is proposed. Based on the control, the different stable periodic orbits are obtained and by adjusting the feedback coefficients and the feedback interval.As example,the Rossler system is researched numerically.The results show that the method can control effectively the system,and the range of control is broad.
