The Parametrization of All Stabilizing Smith Predictors for Certain Class of Non-Minimum Phase Time-Delay Plants

In this paper, we examine the parametrization of all stabilizing modified Smith predictors for certain class of non-minimum phase time-delay plants. The modified Smith predictor is well known as an effective time-delay compensator for a plant with large time-delay. Several papers on the modified Smith predictor have been published. In order to express the past studies of modified Smith predictor in an uniform manner, Yamada and Matsushima gave the parametrization of all stabilizing modified Smith predictors for minimum phase time-delay plants. However, the method by Yamada and Matsushima cannot apply for non-minimum phase time-delay plants. The purpose of this paper is to propose the parametrization of all stabilizing modified Smith predictors for certain class of non-minimum phase time-delay plants
