中文摘要：
针对Bragg路声光双稳系统的混沌态，提出了利用外部微扰反馈的方法对其进行控制。数值分析表明，适当选择反馈强度可将原本混沌的系统控制到各种不同的周期轨道上，同时计算了噪声对系统状态演化的影响。结果表明，系统对小幅度噪声具有一定抗干扰能力。
英文摘要：
In this paper, a method of chaos control in Bragg acousto- optic bistable（AOB） system is proposed by using external perturbation feedback for chaotic state. Results of numerical simulations show that the system can be controlled to different stable periodic orbits by choosing feedback intensity properly. The effect of noise to state evolvement is also analyzed. The results indicate that the system has the ＇ability of anti - jamming for small noise.
