A model of the control function in the case of constant effort of the cardiovascular system

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.
