ASPR Based Output Feedback Control with an Adaptive Predictive Feedforward Input

This paper deals with a control system design problem based on the ASPR-ness of the controlled systems. It is well known that one can design an output feedback control system if the controlled system satisfies ASPR conditions. Unfortunately, however, the ASPR conditions impose a severe restriction to the controlled systems. The introduction of a parallel feedforward compensator is one of the simple strategies to alleviate the ASPR restrictions. In this paper, we propose an output tracking control system design scheme for ASPR augmented systems with the PFC by applying an adaptive predictive control input as a feedforward input.
