基于模糊PID的恒张力控制系统设计

The Design of Constant Tension Control System Based on the Fuzzy-PID

在带材加工和卷曲过程中,对带材的张力控制关系到带材的品质和质量。本文设计了基于模糊PID控制算法的电液比例恒张力控制系统,以可编程控制器(PLC)作为主控器,在分析常规PID控制器的基础上,采用了模糊PID控制算法对系统控制,实现PID控制参数的在线自整定。经过实验研究,模糊PID控制系统比常规PID控制系统相应快,调整能力强,鲁棒性好,有效的改善了控制效果。

The tension cotroll of the belt material is very important when the belt material is produced and curled. Article. The article designed a electr-hydraulic proportional control system of constant tension, which the PLC was the main cotroller. And based on the traditional PID cotroller, the fuzzy-PID was adopted, so the cotroller parameter of interger was chieved automaticly. By study of experiment, the fuzzy-PID cotrol system has the some merit compared with the PID cotroll system, such as responlity, adjustment ability.
