Abstract

Although the cardiovascular process model is well formed, the shape of the control function which complements the ensemble as a control system is still an open question. The paper presents a new structure of the ensemble that handles the control mechanism using a two terms control signal and offers a simple solution for modeling the response of the cardiovascular system to constant exercise. The proposed model is implemented and simulated in Matlab-Simulink. The heart rate and arterial systemic pressure responses to the exercise scenario are compared with the ones obtained by the implementation of cardiovascular system as a solution of a linear quadratic control problem.
