1.导言时滞对反馈调节系统的有害影响已众所周知.给带时滞过程提供的特殊调节措施一“Smith预测”或“Smith线性预测”受到了充分的重视.一些模拟的和实验的研究表明,Smith预测器可以比常规调节带来重要的改进.近年来,预测器已扩展至采样系统和多变量系统. 1. Introduction The detrimental effects of time-delay on a feedback regulation system are well known, and special adjustments to the time-lag process are given a “Smith Prediction” or “Smith Linear Prediction.” Some simulated sum Experimental studies have shown that Smith predictor can bring important improvements over conventional tuning. In recent years, predictor has been extended to both sampling and multivariable systems.
