采用一种简便易行的控制方法，对一个由延时微分方程描述的无穷维光学系统的双稳行为进行控制，成功地稳定了滞后循回曲线中不稳定的中间态；抑制了该系统的Ｈｏｐｆ分岔和倍周期分岔．这些数值控制结果均是在模拟该光学系统的实验条件下完成的
By adopting a simple and easy control method, the bistable behavior of an infinite dimensional optical system described by delay differential equation is controlled and the instability intermediate state in the hysteresis loop is successfully stabilized. Hopf bifurcation and doubling period bifurcation. The results of numerical control are all simulated under the experimental conditions of the optical system
