锌空电池极片张力PID控制系统研究

摘要

锌空电池作为一种高效、无污染和可回收利用能源,成为当今世界电池领域开发的热点,有巨大市场前景.在锌空电池生产线中,张力对保证产品质量有重要的作用.按照张力产生原因不同,对锌空电池极片生产线控制系统进行模糊控制器的设计.以电池极片生产线的张力控制为研究对象,以开卷机构为例,建立张力控制系统的数学模型；并将模糊PID算法应用于张力控制系统中,仿真研究结果表明在控制器中引入模糊PID控制,系统的性能得到了很大的改善,能很好的实现恒张力运行.%As an efficient,no pollution and recycled kind of energy,Zn-air battery is regarded as the hotspot of its field and has market prospects.Tension in zinc-air battery production line plays an important role in ensuring the quality of products.It makes tension control of electrode of zinc-air battery production line as research object.According to the different cause of tension,designing fuzzy controller of the control system.Taking uncoiling mechanism as an example,it establishes a mathematical model of the tension control system; and applies fuzzy PID algorithm to tension control system.Simulation results show that using fuzzy PID control in the controller,the performance of the system gets a big improvement; it can realize controlling of constant tension.
