A Novel Design of an Adaptive PID Controller for Cardiac Pacemaker Achu Govind K. Aravind Sekhar Vinod B.- Dept. of Electronics and Communication, Mohandas College of Engineering, Kerala University, Trivandrum- Kerala, India
Biomedical engineering deals with the application of various concepts of engineering in the field of medicine and biology mainly for health care purposes thereby improving patients quality of life. Out of the various techniques, the primary focus is to develop a reliable and optimized technique for electro simulation of heart. The present work deals with an improvement in the design of control system for regulating the heart rate of a pacemaker in an efficient way. An Adaptive PID controller based on the Delta rule and Adaptive Correction Factor is proposed in this paper. The Adaptive PID controller is implemented using an Adaptive Loop incorporating MIT rule with the Delta rule. The PID parameters are modified by an Adaptive Correction Factor. Simulation results were performed on the developed cardiovascular system of humans and results show that the proposed adaptive PID controller produces superior control performance than conventional PID controller. Simulations were done in Matlab/Simulink.
Keywords: Adaptive PID Controller, Adaptive Correction Factor, MIT Rule, Delta Rule, Pacemaker, Heart Rate.
