Abstract

The main objective of this paper is to design the digital PID controller for injecting insulin externally to the diabetic patient for maintaining a healthy blood glucose level. We have designed PID controllers using various tuning rules for examining the best performance in terms of different time response parameters like Overshoot, settling time & rise time, etc. Various tuning methods used for designing PID in this paper are the Ziegler Nichols method and the IPDT method. We have also made approximate mathematical modelling of blood glucose levels. Finally, we convert the conventional PID controller into a digital PID controller.
