“…The real system represented by the the block "Gas exchange dynamics", has a power input and two outputs, which can be all measured in practice, but here we assume available measurements of the input and the oxygen consumption. A validated model of gas exchange dynamics (see [6]), is used for the implementation of the observer.…”

This paper presents a set-membership observer for the estimation of carbon dioxide production during cycling. The observer uses measurements of oxygen consumption and power at pedal level together with a discrete-time linear model of gas exchange dynamics. The real process is assumed to be disturbed by unknown but bounded disturbances. The proposed observer provides a deterministic interval which contains the real state. Since the excess of carbon dioxide production is linked to the overtake of the anaerobic threshold, the observer can be applied to predict the physiological state of the cyclist by using a reduced number of gas exchange sensors. The methodology is illustrated and validated using experimental data.
