طراحی راهبردهای کنترل پیشرفته برای سیستم قلب و عروق

Cardiovascular diseases are chief causes of anguish and mortality in the developed countries. Bio-medical engineering deals with the application of various approaches of engineering in the field of medicine and biology mainly for health care purposes thereby improving patient’s quality of life. Out of the various techniques, the important focus is to develop a reliable and optimized technique for simulation of electric activity of heart. In an effort to make such a technique this work describes the design of a control system for regulating the Heart Rate (HR) for pacemaker in an efficient way. The overall control system to be developed, in this work is considered to be composed of cardiovascular system duly triggered by an intelligent pacemaker system as operated in a closed loop manner with unity negative gain in the feedback path. A conventional controller based on Proportional, Integral and Derivative (PID) is designed with the help of Zeigler-Nichols, Neural controller and Adaptive control schemes. The simulations have been carried out using MATLAB/SIMULINK. By the way of comparative study of simulated results of different control techniques it is found that the overall response of adaptive controller is better than the conventional PID controller.
