基于小波的热连轧轧辊偏心控制

The Wavelet-based Roll Eccentricity Control for Hot Rolling

本文提出了一种用于热连轧的基于小波分析的轧辊偏心控制方法,该方法首先根据偏心信号的特点,利用小波对轧制力信号进行多分辨分解,把偏心从轧制力信号中提取出来,然后在控制中对偏心进行补偿。仿真试验表明该方法是有效的,为继续深入这方面研究与应用提供了良好的基础。

This paper presents a novel Wavelet-based Controller （MRWC） used in roll eccentricity control for hot rolling. According the characteristic of eccentricity signal, the roll force signal is decomposed using wavelets to identify the eccentricity,then compensate for the roll eccentricity signal and remove other uncertainties in control design. The work presents here is a first step in this direction. Simulation results are shown to validate the control strategy.
