Unwinding tension control system of conveyor belt former

针对传送带单线成型机放卷过程线绳张力不稳定、排线不均匀等问题,设计传送带单线成型机的放卷张力控制系统,建立该放卷张力控制系统的数学模型,并根据自抗扰控制技术对张力控制器进行设计,最终提出基于差分进化算法的自抗扰控制器参数优化方法。研究结果表明:所设计的放卷张力自抗扰控制器比传统的PID控制器具有更好的鲁棒性和抗干扰性,更能适应传送带单线成型机的张力控制。

A structure and control strategy in the unwinding tension control system of conveyor belt former was studied to enhance the tension stability and the uniformity of cords. A model of unwinding system was established according to the designed structure. And according to the model, the active disturbance rejection controll techique was used to design the tension controller, and then differential evolution algorithm was presented for tuning the parameters of the controller automatically. The results show that the proposed active disturbance rejection controller has better internal robustness and interference immunity than traditional PID controller in tension controll.
