摘要
在工业生产过程中普遍存在着时滞特性,尤其是对于大滞对象的控制一直以来都是难题.大时滞的存在严重影响了系统的控制效果和稳定性.因此,控制大时滞过程一直是控制理论研究中的重要课题.内模控制方式对于时滞系统具有良好的参数调节性能,并且通过引入滤波器可以使系统具备较好的鲁棒性.Smith预估控制是一种有效的时滞补偿方法,但对于参数变化较为敏感.PID控制具有结构简单、原理清晰、适应性强和鲁棒性强的优点.在本文中,我们主要通过仿真比较来研究了三种控制方式对大时滞过程的控制效果.
Abstract
In industrial production processes,there is a common presence of time delay characteristics,especially for controlling large delay objects,which has always been a challenge.The existence of large time delays significantly affects the control effectiveness and stability of the system.Therefore,controlling processes with large time delays has been an important topic in control theory research.Internal model control demonstrates excellent parameter adjustment performance for time-delay systems and can enhance system robustness by implementing filters.Smith predictor control is an effective method for time-delay compensation but is sensitive to parameter changes.PID control has the advantages of simplicity in structure,clarity in principles,strong adaptability,and robustness.In this paper,we primarily study the control effectiveness of the three control methods for processes with large time delays through simulation comparisons.
