The heart rate regulation problem is addressed for the well-known second order nonlinear model of the human heart rate response during treadmill/cycle-ergometer exercises. The mainly restrictive stability & global attractivity constraint in the literature, being constituted by an inequality involving four constant parameters of such a nonlinear model, is definitely removed. Nonlinear analytical arguments and design steps are innovatively presented to achieve heart rate regulation when model parameters satisfy the so-called 'instability constraint', with just stability & local attractivity properties being involved. Experimental results are included to illustrate all the theoretical derivations. (C) 2021 Elsevier Ltd. All rights reserved.

Abstract
The heart rate regulation problem is addressed for the well-known second order nonlinear model of the human heart rate response during treadmill/cycle-ergometer exercises. The mainly restrictive stability & global attractivity constraint in the literature, being constituted by an inequality involving four constant parameters of such a nonlinear model, is definitely removed. Nonlinear analytical arguments and design steps are innovatively presented to achieve heart rate regulation when model parameters satisfy the so-called 'instability constraint', with just stability & local attractivity properties being involved. Experimental results are included to illustrate all the theoretical derivations. (C) 2021 Elsevier Ltd.
