摘　　要：针对经编用电子送经系统响应滞后,高速切换横条明显等问题,通过将模糊控制与普通PID控制相结合,设计了一种经编电子送经系统。利用模糊PID控制算法,通过模糊PID实时修正经轴电动机速度,实现送经PID参数的在线调整,明显提高系统的动态响应性能。使用MatLab仿真,将模糊PID控制算法与普通PID算法的控制效果进行对比,结果表明,与普通PID控制相比,模糊PID控制算法可有效提高经轴电动机响应速度,降低超调量和减少稳态误差,优化经编电子送经系统的整体性能。In view of the electronic yarn let-off system response lag and obvious stripe when high-speed switching during warp knitting,a kind of fuzzy PID algorithm for the electronic yarn let-off system is developed by combining fuzzy control with common PID control.The real-time correcting of the warp beam motor running speed is carried out through the fuzzy PID technology,so that the PID parameters of yarn let-off system are adjusted online.Therefore,the system’s dynamic performance is greatly improved.By use of MatLab,PID control and fuzzy PID control are simulated,and their results are compared.When compared with common PID control,the fuzzy PID control can effectively raise the response speed of warp beam motor,reduce overshoot and steady-state errors,and optimize the overall performance of the electronic yarn let-off system.
