摘　　要：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．Abstract Using a very easy and very convenient method, we controlled the unstable intermediate state of the hysteresis loop in an optical bistable system governed by a delay differential equation. Simultaneously, we also stabilized and suppressed the Hopf bifurcation and double period bifurcation by this technique. All the numerical results are obtained by simulating the experimental condition of Gibbs et al.
