Abstract:
In this paper, a mathematical based model for stabilization of human heart using two-Degree of Proportional Integral and Derivative (2-DOF PID) controller has been presented. The mathematical model representing the periodic action of the human heart is presented in transfer function based on hydro-electromechanical characteristics of the cardiovascular system in terms of four components: peacemaker, heartbeat, circulatory system, and feedback sensor. Simulation conducted in MATLAB/Simulink revealed that the mathematical model produced a response similar to electrocardiogram (ECG) recorded for normal heartbeat. With the 2-DOF controller, the system was able to stabilize the heart against the effect of noise and disease.
