摘要: Smith预估控制能够有效克服系统时延,在过程工业中有着广泛应用。然而这种控制方法对系统建模精度要求很高,当出现系统不确定性和外部干扰时,Smith预估控制性能会显著降低。本文对Smith预估控制器进行了简单介绍,并对Smith预估控制器结构改进的研究、参数整定方法的研究和与高级控制算法结合的研究等进行了介绍和总结。

Abstract: Smith-predictor controller can eliminate the effect of time delay,which is extensively used in process industry. However,this control approach depends heavily on modeling precision. The control performance will be deteriorated in the presence of system uncertainty and external disturbance. Therefore,a lot of researches have been carried out in improving the control performance of Smith-predictor controller. This review summarizes the achievements in the modification of Smith-predictor controller,and prospects for future research are proposed.
