Stabilization and control of unstable first order linear delay systems

This work considers the problem of stabilization and control of first order linear systems subject to input delay.As it is known,the stability analysis of this type of systems becomes difficult due to the term dead time considered.To solve the stabilization problem as a first step are presented the conditions that assures the stability of the systems in closed loop with a proportional feedback,these condition are derived with a novel methodology based on a discrete time approach.The stability conditions are used to design an observer (predicting) scheme that provides adequate convergent error.The proposed scheme results similar to the traditional Smith Predictor that can be used on the case of stable systems.The observer scheme is complemented by the use of a PI compensator to follows step reference signals.
