阐明了Smith预估控制对时滞失配鲁棒稳定性弱的机理。引入近似Smith预估器来消除原因。证明了近似Smith预估控制鲁棒稳定的充分条件。结果表明，与原Smith预估器相比，该预估器的稳定区域变宽。
This paper clarifies the mechanism of weakness of Smith predictor control about robust stability to the delay mismatch. The approximate Smith predictor is introduced to remove the cause. The sufficient condition for robust stability of the approximate Smith predictor control is proved. It is shown that the stability area becomes wider in comparison with the original Smith predictor.
