Optimal digital PID controller design for regulating blood glucose level of type-I diabetic patients

Abstract

The main objective of this paper is the design and implementation of an optimised PID controller using Xilinx System Generator for the regulation of blood glucose level of type-I diabetic patients. In this work, the Bergman model is used to describe diabetic patient model. The particle swarm optimisation algorithm is used to find the optimal values of the PID controller parameters. To determine parameters that meet closed loop system of the blood glucose regulation performance specification and to show its effectiveness, the proposed PSO-PID controller is compared to the classical PID. Finally, Xilinx System Generator is used to implement the digital optimal PID controller and verify its capability.
