Circuit Implementation of Coronary Artery Chaos Phenomenon and Optimal PID Synchronization Controller Design

Abstract

This study aimed at the implementation and synchronization control of cardiac circuit. First, the MATLAB‐Simulink was used to simulate the dynamic behavior of cardiac chaotic circuit, and simple electronic modules were used to implement the cardiac system. Then the Particle Swarm Optimization (PSO) was used to seek for the proportional, integral, and derivative gains of optimal PID controller, and the PID controller which could synchronize the slave cardiac circuit and the master cardiac circuit was obtained, in order to synchronize the master/slave chaotic cardiac circuits. This method can be provided for cardiac doctors to diagnose and medicate cardiac abnormality.
