Designing adaptive integral sliding mode control for heart rate regulation during cycle-ergometer exercise using bio-feedback

This paper considers our developed control system which aims to regulate the exercising subjects´ heart rate (HR) to a predefined profile. The controller would be an adaptive integral sliding mode controller. Here it is assumed that the controller commands are interpreted as biofeedback auditory commands. These commands can be heard and implemented by the exercising subject as a part of the control-loop. However, transmitting a feedback signal while the pedals are not in the appropriate position to efficiently exert force may lead to a cognitive disengagement of the user from the feedback controller. To address this problem this paper will employ a different form of control system regarding as “actuator-based event-driven control system”. This paper will claim that the developed event-driven controller makes it possible to effectively regulate HR to a predetermined HR profile.
