This paper presents an adaptive output feedback control solution using closed-loop reference models for plants with direct feedthrough. A closed-loop reference model both generates a state estimate to be used for feedback control and provides a reference for the adaptive controller. The proposed controller consists of a linear quadratic regulator baseline controller and integral action augmented with adaptive components, and it is proved to stabilize a class of linear relative degree-zero plants with parametric uncertainties and disturbances. This paper proposes a systematic design of the closed-loop gain that allows for an increase size of parametric plant uncertainties. A simulation example and the control design of the lateral dynamics of a highly agile model aircraft are presented.
