Modified Artstein Predictor for LTI Systems with Dead Time and Unkown Disturbances

[摘要] This paper presents a modified Artstein-based predictor for the control of LTI systems with dead time and bounded disturbances. A generalized condition is presented in order to achieve null prediction error in the presence of constant disturbances. The proposed predictor can also be explored to achieve null prediction error in the presence of sinusoidal disturbances or to improve disturbance rejection for processes with long dead time. Comparative simulation examples are used to illustrate the usefulness of the proposed approach...
