Tracking performance of non-minimum phase systems under the continuous deadbeat condition is handled in this paper. It is well known that tracking performance is constrained and is difficult to achieve good transient response for the plant with unstable zeros. It seems that the deadbeat time and minimum undershoot by controller has some relation. In this paper, we derive analytical solution of a minimum undershoot for plants with one unstable zero when we want to achieve tracking control for the step reference. The effectiveness is illustrated using numerical simulations.
