碳纤维角联织机卷取系统张力网络化控制研究

针对碳纤维角联织机卷取系统中的张力控制问题,对卷取系统进行动力学分析并建立动力学模型;在考虑网络诱导时延、数据包丢失及网络带宽占有率等因素的基础上设计一种自适应模糊PID控制器,将此控制方法与常规的PID控制方法进行仿真对比。结果表明,在同时存在网络诱导时延、数据包丢失及网络带宽占有率的情况下,自适应模糊PID控制方法超调量小、输出张力波动小、跟踪效果良好、系统稳定性强,具有更好的控制效果。

Study on Tension Network Control of Take-up System of Carbon Fiber Angle Loom

Aiming at the tension control problem in the take-up system of carbon fiber angle loom, the dynamic analysis of coiling system is carried out and the dynamic model is established. An adaptive fuzzy PID controller was designed based on factors such as network induced delay, packet loss and network bandwidth occupation. This control method is compared with the conventional PID control method by simulation. The results show that under the conditions of network induced delay, packet loss and network bandwidth occupancy, the adaptive fuzzy PID control method has small overshoot, small output tension fluctuation, good tracking effect, strong system stability and better control effect.
