利用反馈技术实现了环形腔光折变振荡器的时空混沌控制。数值计算结果表明,定值反馈和变量反馈技术均可实现时空混沌控制。在振荡器系统参数确定的条件下，利用定值反馈实现了对时空混沌的控制，同时系统存在反馈系数的最小值和反馈光强度的最大值。反馈技术不仅可以实现一维的时空混沌控制，还可以实现二维的控制，而且两者控制结果相似。

With the feedback technique, the spatiotemporal chaos is controlled in the photorefractive ring oscillator. Numerical simulation results show that the fixed value feedback and variable feedback technologies both can realize the control of spatiotemporal chaos. When the photorefractive ring oscillator system parameters are confirmed, the control of spatiotemporal chaos is realized based on the fixed value feedback. In addtion, the system has the minimum feedback coefficient and the maximum feedback light intensity to realize spatiotemporal chaos control. So the reasonable feedback coefficient and feedback light intensity must be chosen in order to control the spatiotemporal chaos. The feedback technology can not only be used to realize the one-dimensional spatiotemporal chaos control, but also the two-dimensional control, and simultaneously the two control results are similar.
