Fast-rate adaptive output feedback control with adaptive output estimator for non-uniformly sampled multirate systems

This paper deals with an adaptive output feedback control design problem for non-uniformly sampled multirate systems with a fast uniform input updating rate and slow non-uniform output sampling rates. A design scheme of a fast-rate adaptive output feedback control at the fast sampling period of the input updating rate will be proposed for non-uniformly sampled systems using an adaptive output estimator. The proposed adaptive output feedback control is designed by using only measured outputs of slow rate samplings and fast rate updating input. We also analyze the stability of the obtained fast rate output feedback control system briefly based on ASPR properties of the controlled system.
