Control of a model of human heart

Participants : Frédéric Mazenc, Michael Malisoff [Louisiana State University] , Marcio de Queiroz [Louisiana State University] .

We worked on the control of human heart rate during exercise [27] , which is a problem that has implications for the development of protocols for athletics, assessing physical fitness, weight management, and the prevention of heart failure. We provided new stabilization techniques, based on the notion of tracking, for a recently-proposed nonlinear model for human heart rate response that describes the central and peripheral local responses during and after treadmill exercise. The control we proposed respect the sign constraint imposed by the model and we proposed observers to cope with the case (important from a practical point of view) where some of the variables are not measured.
