Parallel feedforward compensator design and ASPR based adaptive output feedback control for a time-delay system

This paper deals with a design problem of a parallel feedforward compensator (PFC) for designing a stable adaptive output feedback control of systems with a time delay. To design an adaptive output feedback control, the introduction of a PFC which renders the resulting augmented system with the PFC ASPR has been considered. However, the PFC design scheme for the time delay system have not been provided. In this paper, a PFC design method based on the idea of Smith predictor will be proposed and the stability of the adaptive output feedback control for time-delay systems with the proposed PFC will be analyzed.
