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.
