| 摘要:针对纸张横幅（CD）定量过程中测量点与稀释水阀执行器之间的对位问题，本研究基于冲击实验进行CD定量过程建模与识别，辨识执行器的响应中心、推算响应宽度，确立执行器与正下方测量点之间的映射表；基于物理映射数据的聚类分析识别对位模型。通过随机检验测试，验证对位关系并实现偏移补偿纠正。该方法能有效解决纸张横幅定量控制中执行器对位问题，确保定量横向控制系统的有效发挥，为工程应用提供参考。 |
| Abstract:Aiming at the problem of alignment between the measuring data and the dilution water valve actuator in the process of cross directional basis weight of paper-making. CD process modeling and identification were carried out based on the impact test， the response center of the actuator was identified， the response width was calculated， and the mapping table between the actuator and the measuring point was established. Cluster analysis based on physical mapping data identified the contrapuntal model. Through random inspection test， the alignment relationship was verified and offset compensation correction was realized. This method could effectively solve the problem of actuator alignment in the process of cross directional basis weight of paper-making， which improved the adjustment accuracy of CD profile control and thus improves the paper quality. It can provide reference for engineering applications. |
