The Application of Adoptive Control to the Tension-AGC System on Cold Tandem Mill
-
摘要: 本文分析了冷連軋機張力厚控系統,表明該系統是時變動態系統,從而確定使用最小方差自校正調節器應用于該系統。對實際系統進行了辨識模型并在此基礎上進行了仿真研究。結果表明了自校正調節器控制效果優于PID調節器,而漸消記憶的遞推最小二乘法是一種較好的在線辨識算法。將自校正調節器應用于實際張力厚控系統,使得帶銅厚差得到明顯改善。Abstract: The analysis of tension AGC system in the tandem cold mill shows that it is a time-varing dynamic system, so that the minimum variance self-tuning regulator is used. After the system is identified and simulated, the results how that the control effect of self-tuning regulator is better than that of PID regulator and the recursive least square with forgetting factor is a better identification algorithm. The application of self-tuning regulator in an actual tention AGC system shows that the gauge deviations of the controlled strip are greatly decreased.
