摘　　要：针对光纤环缠绕过程中对张力控制系统恒定小张力、调整时间短、响应快的特点,基于速度差控制张力的原理,建立了以工业控制计算机和可编程多轴运动控制器为控制核心,交流伺服电机为执行元件的间接张力控制系统.并对精密张力控制系统及控制方法进行了分析,建立了PID控制器的闭环张力控制系统数学模型,对张力控制系统进行仿真实验,分析了控制方案的可行性.仿真实验表明,PID控制器在张力控制系统中响应速度较快,超调小,随着时间增加,系统稳态误差接近零,能满足光纤陀螺缠绕机对恒定小张力的要求,为张力控制系统的分析与研究提供了必要的理论依据.In the process of fiber coil winding, the tension control system has characteristics of low- consistent tension, short adjustment time and rapid response. The accurate tension control system was established based on the principle of the speed difference control tension, which took industrial computer and programmable multi-axis motion controller as the control core and took AC servo motor for the implementation. The closed-loop tension control system was modeled with PID controller, simulated, and experimentally validated. The results of the simulation experiment show that PID controller has characteristics of rapid response and small over rate in the tension control system. As time increases, the steady-state error closes to zero, which meets the requirement of low-consistent tension control in fiber optic gyro winding machine. The results can provide a necessary theoretical basis to analyze and study the tension control system.
