Abstract

Abstract – In this paper, the design of robust blood glucose controller in diabetes using H-infinity technique is presented. The Particle Swarm Optimization (PSO) method is used to tune the specific structure controller parameters subject to H-infinity constraints. The Bergman model is used to represent the artificial pancreas. This model is one of the more widely used models of the effect of insulin infusion and glucose inputs on the blood glucose concentration. The results show the effectiveness of the designed controller in controlling the behavior of glucose deviation to a sudden rise in the blood glucose. The proposed controller can effectively attenuate the blood glucose deviation to 0.15. This value of attenuation makes the proposed controller superior to the other controllers in previous works. Matlab 7.11 is used to demonstrate the simulation results.

Abstract

Abstract – In this paper the design of robust Active Queue Management (AQM) forcongestion control in computer networks is presented. The Ant Colony Optimization(ACO) method is used to tune the parameters of PID controller subject to H-infinityconstraints. The nonlinear dynamic model for multiple TCP flows control is developedbased on fluid-flow theory. The designed controller provides good tracking performancein the presence of wide range of system parameter uncertainty. NS2 package is used toperform the nonlinear simulation of the system.
