摘要
冷轧机是冶金板材成形领域重要的设备之一,其在运行过程中产生的扭振问题对冶金板材的质量控制影响很大,为此开展了基于系统性能调控约束(PPC)的冷轧机振动控制优化分析。在建立冷轧机抗扰动振动控制系统模型的基础上,开展工况仿真分析。研究结果表明:在外部扰动情况下,没有PPC约束的自适应控制器出现了大幅振荡,设置PPC约束后达到了更优收敛状态,系统呈现稳定运行状态,该研究只需设置合适的性能域便能够使系统达到理想控制状态,简化了控制器操作性能。
Cold rolling mill is one of the important equipment in the field of sheet metal forming.The torsional vibration caused by the rolling mill during operation has a great influence on the quality control of sheet metal,because the optimization analysis of cold rolling mill vibration control based on system performance control constraint(PPC)has been carried out.Based on the establishment of anti-disturbance vibration control system model of cold rolling mill,the simulation analysis of working condition is carried out.The results show that the adaptive controller without PPC constraint oscillates greatly under the presence of external disturbance factors.After the PPC constraint is set,a better convergence state is achieved,and the system runs stably.In this study,only a very good performance domain can be set to achieve the ideal control state of the system and simplify the controller operation performance.
