congestion control. The focus is on so-called anti-windup techniques to provide constructive
Linear Matrix Inequalities (LMI) conditions for the synthesis of anti-windup compensators
while guaranteeing the stability of the closed-loop system. In addition, some interesting
extensions and open problems are discussed, such as nested saturations, the presence of
timevarying delays in the state or the input, and anti-windup for non-linear systems. Finally …
