论文摘要
表明混乱发生在单硅晶体拉拔器的柔性轴旋转式（FSRL）系统中。然而，混乱对单硅晶体产生的质量有害。因此，应该被抑制。理论上已经提出了许多混乱控制方法，甚至在应用中使用了一些混乱方法。对于表现出有害混乱的实用植物，特定区域的工程师通常面临着识别混乱并使用适当方法抑制它的挑战。但是，尽管有现有方法，但FSRL系统中的混乱控制方法选择并不是一项琐碎的任务。例如，对于OGY方法，如果找不到可调节的参数，则无法应用OGY方法。正在提出一种冲动的控制方法，该方法有效地抑制了FSRL系统中的混乱。使用Melnikov方法获得控制参数的选择。仿真结果显示了我们的理论分析的正确性以及所提出的混乱控制方法的有效性。
Chaos is shown to occur in the flexible shaft rotating-lifting (FSRL) system of the mono-silicon crystal puller. Chaos is, however, harmful for the quality of mono-silicon crystal production. Therefore, it should be suppressed. Many chaos control methods have been proposed theoretically and some have even been used in applications. For a practical plant displaying harmful chaos, engineers from a specified area usually face with the challenge to identifying chaos and to suppressing it by using a proper method. However, despite of the existing methods, chaos control method selection in the FSRL system is not a trivial task. For example, for the OGY method, if one cannot find a practical adjustable parameter, then the OGY method cannot be applied. An impulsive control method is being proposed which is efficiently able to suppress chaos in the FSRL system. The selection of the control parameters is obtained by using the Melnikov method. Simulation results show the correctness of our theoretical analysis and the effectiveness of the proposed chaos control method.
