Abstract: This paper deals with a design problem of a performance-driven adaptive output feedback control system with a parallel feedforward compensator (PFC) designed for making the augmented controlled system ASPR. In the proposed adaptive control system, for systems in which the properties are changing during the operation, the PFC will be redesigned through FRIT approach and the output feedback gain will be readjusted according to a performance index.

Keywords: adaptive output feedback; almost strictly positive real; ASPR; fictitious reference iterative tuning; FRIT; parallel feedforward compensators; PFC; feedback control; adaptive control.
