基于自调整模糊PID的光纤张力控制器设计

Design of tensioncontroller of optical fiber based on self-adjusting fuzzy PID

光纤管线环绕张力是影响光纤环品质的重要因素。受光纤材料本身光滑、易折以及光纤张力过大会引起传输损耗等因素影响,在光纤环绕过程中光纤张力需要精确稳定在一个极小的张力值上。针对光纤环绕过程的特点,设计出了以C8051F340单片机为核心处理器基于自调整模糊PID算法的张力控制器,以满足该过程对光纤张力的精确控制要求。实际光纤绕制过程表明,采用自调整模糊PID控制算法设计的张力控制器在运行稳定性、控制精度,特别是在系统的鲁棒性方面明显优于传统的PID控制器。

The tension when coiling the optical fiber is the main factor in the qulity of optical fiber. The fiber material itself is smooth, easily fold and the transmission losses will be caused if the fiber tension over the limit. Therefore, in the process of optical fiber around, the fiber tension need to stable at a very small value. Aiming at the characteristics of optical fiber around process, a new type tensioncontroller was designed, using C8051F340 as the core and based on the self-adjusting fuzzy PID. The requirements of precise control of optical fiber tension were satisfied. The results of the actual control process show that, the self-adjusting fuzzy PID controller performance is better than traditional PID controller in terms of stability and control accuracy, especially the robustness of the system.
