矫正织物蛇行跑偏运动的智能纠偏系统

针对带形织物在加工生产过程中存在的蛇行跑偏问题,为提高动态纠偏性能和克服纠偏执行电动机的零位振荡,采用以直流伺服电动机驱动的摆动辊为纠偏执行机构,在理论分析的基础上提出一种以跑偏量的前馈控制和对系统偏差进行智能PD反馈调节的复合纠偏控制算法,并用MatLab仿真验证了该方法的优点,同时介绍了基于高速混合信号处理器C8051F020的纠偏控制器的技术实现方案。该系统经实际应用表明,纠偏迅速、平稳,很好地解决了纠偏执行电动机的零位振荡问题。

Intelligent control system for edge position deviation of narrow fabrics

Focused on the S-shape deviation problem in the narrow fabric production process, this paper introduces an intelligent control system with DC servomotor as the actuator for an intermediate guide roll system. To improve the dynamic performance of the deviation control system and solve the motor vibration problem, the deviation control algorithm is proposed, which is related to intelligent PD feedback control combined with the feed-forward regulation for the system deviation, and its MatLab simulation result shows its good performance and advantages. Furthermore, a technical approach for the deviation controller using highspeed mixed signal micro-controller C8051F020 is presented The system is applied in the intermediate guide roll system, and the application result indicates that this system is characterized by fast response and steady operation and it is a good solution for the motor vibration.
