摘要: 厚度精度是衡量板带材轧机生产质量的一个重要标志。而高精度的板带材出口厚度需要通过厚度自动控制系统实现。为了提高成品板带材厚度精度,将模糊控制、生物免疫系统的反馈机理和传统PID控制相结合,构造了带钢厚度控制系统的模糊免疫PID控制器,利用免疫算法和模糊逻辑在线调整PID参数。仿真结果表明,基于模糊免疫PID控制器的轧机厚度控制系统在响应速度、超调量、稳定性和鲁棒性等方面均优于基于常规PID控制器的厚度控制系统,能够显著提高出口厚度精度。

Abstract: Thickness precision is an important index of measuring the products quality of a plate and strip mill. The high accuracy of strip thickness is needed to be realized through the thickness automatic control (AGC) system. In order to improve the thickness accuracy of the finished strip,fuzzy control,feedback mechanism of biological immune system and traditional PID control are combined in this paper to construct a fuzzy immune PID controller for strip thickness control system,using immune algorithm and fuzzy logic to adjust PID parameters on-line. Simulation results show that the fuzzy immune PID controller were better than thickness controller system based on conventional PID controller in response speed,overshoot,stability and robustness. It can improve the precision of the export thickness remarkably.

Key words: thickness control, fuzzy immune, cold rolling mill
