The purpose of this paper is to design congestion controllers for TCP/AQM networks using state predictive control and illustrate effectiveness of designed congestion controllers via SIMULINK and the ns-2 simulator. Linearized models of TCP/AQM networks can be described as linear systems with an information delay simply. Using state predictive control, these linear systems with an information delay are equivalent to linear systems with no delays. Thus congestion controllers (AQM mechanisms) can be designed using the linear control theory. In this paper, LQ control with an observer is adopted for linear systems with no delays which describe linearized systems of TCP/AQM networks.
