Abstract
In this paper, we examine a design method for a
modified Smith predictor for minimum-phase timedelay
plants. The modified Smith predictor is well
known as an effective time-delay compensator for a
plant with large time delays, and several papers on
the modified Smith predictor have been published.
However, the parameterization of all stabilizing modified
Smith predictors has not been obtained. If this
can be obtained, we can express existing proposals for
modified Smith predictors in a uniform manner, and
the modified Smith predictor can be designed systematically.
The purpose of this paper is to propose
the parameterization of all stabilizing modified Smith
predictors for minimum-phase time-delay plants. The
control characteristics of the control system using
the parameterization of all stabilizing modified Smith
predictors are also given. Finally, numerical examples
for stable plants and unstable plants are illustrated
to show the effectiveness of the proposed parameterization
of all stabilizing modified Smith predictors. |
