Abstract: During the last years, the Internet Application (Remote Flexible Control and Instrumentation, Telecontrol...) has retained the attention of Control researchers for modeling and studying the congestion control of TCP/IP (Transfer Control Protocol/Internet Protocol) networks. The controllers proposed in the literature such as RED (Random Early Detection) or PID (Proportional Integrate Derivative) or H2/H¡Þ (H2 norm/H infinity norm), give good performance under certain conditions, but they become unstable if the input delay or/and the parameters of the networks change beyond some limits. Different papers have treated the H2/H¡Þ robust control problem, but in this paper, adding to formulate and solve the standard robust control problem as an H2/H¡Þ, and synthesize corresponding controllers H2, H¡Þ and mixed sensitivity controller, we will show how the Routh ¨CHurwitz criterion is weak in front of the small gain theorem, and does not guarantee the robustness of the syst!
