梳棉机的建模与实验研究

在纺织工业中,梳棉过程起着十分重要的作用,这是因为经过梳理的均匀棉条是生产高质量纱线的保证。然而,梳棉过程是一个比较复杂的过程,要想获得比较理想的控制效果,必须要建立起梳棉机的控制模型。为此,提出了在机理分析的基础上,结合实验辩识,在Matlab/Simulink仿真环境中,以方块图的形式首次建立了梳棉机的非线性仿真模型。并采用信号相关性分析技术将实验采集数据和模型模拟数据进行了对比分析。实验证明该仿真模型可以较真实地模拟实际系统,实现简单,便于修改,通用性强。

Modeling and Experiment for Carding Machine

Carding process is of key importance because low irregularity of carded sliver is essential for production of high quality yarn. A model of carding machine is necessary for satisfactory result of control. Based on mechanism analysis and experiment, a nonlinear general model was developed using Matlab/Simulink. And the signal of correlation analysis method was used to prove this model. The experiment result shows the effectiveness of the proposed model.
