Abstract:

Aiming at the requirement of maintaining constant tension in filament winding and the great tension fluctuation in the traditional tension control, the mathematic model is established on the basis of analyzing the tension controller of the pendulum pole. The fuzzy control combined with variable integral PID is taken as the control mode and its feasibility is analyzed. The experiment results show that the control method combining fuzzy control and variable integral PID is applied to the tension control system, the performance is better than the traditional PID control, and the change of the parameter has higher adaptability. It can solve the problems such as large fluctuation of tension in filament winding, low speed of yarn breaking and yarn return.

摘要： 针对纤维缠绕时保持恒张力的要求和传统张力控制中存在张力波动大的特点，在分析摆杆式张力控制器基础上，建立其数学模型；并验证了以模糊控制结合变速积分PID为控制方式的可行性。分别进行了以传统PID与模糊变速PID为控制方式的缠绕实验，实验表明，将模糊控制与变速积分PID相结合的控制方式应用于张力控制系统，性能优于传统PID控制，对参数的变化具有较高的适应性。能解决纤维缠绕时的张力波动大，断纱，回纱速度慢等问题。
