FUZZY PID BASED INTELLIGENT HEART RATE CONTROLLER FOR PACEMAER

Abstract

The combination of medical science and engineering has developed many electro-medical devices such as artificial organs, surgical robots, advance prosthetics, new pharmaceutical drugs and kidney dialysis. Electro-medical devices proved that it has boon for human being. It has not only diagnosed the diseases of patient but also has improved the quality of life of the patients. In last few decades many electro-medical device are introduced one them is pacemaker. A pacemaker is a small artificial electro-medical device that is placed in the chest or abdomen to stimulate the heart muscles to regulate the rhythm of heart in case of any problem in natural heart electric system such as arrhythmias, cardiac arrest etc. Performance of pacemaker depends not only on pacemaker controller circuitry and sensors but also depend on controller which used and its performance.

In this work, we used Fuzzy PID controller with pacemaker and heart to improve the performance of pacemaker in term of minimizing overshoot, rise time and settling time. Fuzzy PID controller is a combination of PID controller and Fuzzy logic controller. That’s way it has characteristics of both controllers. The main advantage of Fuzzy PID controller is that it is used in both linear and nonlinear system. In this work removed overall overshoot and minimized rise time and settling time as compare to previous controllers by using Fuzzy PID controller.
