Varying time delay Smith predictor process controller.
One of the perceived weaknesses of the classical Smith predictor is that the time delay is fixed. For systems with a varying time delay, underestimating or overestimating the time delay significantly degrades control quality. This paper presents theoretical and practical results of applying the Smith predictor with a varying time delay when the nature of the application allows the time delay to be practically computed in real time.
