Based on a linear matrix inequality (LMI) approach, we develop an H controller which guarantees the L2gain of the mapping from the exogenous input noise to the regulated output to be less than some prescribed value for the system. A sufficient condition of the controller for this system is given in term of Linear Matrix Inequalities (LMIs). The effectiveness of the proposed controller design methodology is finally demonstrated through simulation results. It has been shown that the antiHIV vaccines are critically important in reducing the infected cells. </abstract> <index>Open Science Index 65, 2012</index> </article>
