Abstract :
In this paper, we propose a design method of parallel feedforward compensator (PFC) for an adaptive output feedback control and consider an application of the proposed method to a control of magnetic levitation system. In order to obtain a desired PFC which realizes an ASPR augmented controlled plant, PFC parameters are adjusted by the fictitious reference iterative tuning (FRIT) method so as to exist a feedback gain such that the output of the augmented closed loop system with the PFC track the output of the given SPR model by optimizing the performance function that consists of the one-shot experimental input-output data. The proposed PFC design strategy will be applied to adaptive output feedback control of a magnetic levitation system.
