                         or constellation would be an economical choice. From risk-sharing 
                         viewpoint, a number of smaller satellites have a significant 
                         reliability advantage over a bigger one. Generally, one satellite 
                         is subject to two types of uncertainties: structured uncertainty 
                         that represents some satellite parameter variation and the 
                         unstructured uncertainty that represents some kind of the 
                         satellite model error. On the other hand, the Satellite Attitude 
                         Control (SAC) design becomes more vulnerable to uncertainty 
                         disturbances like model error and moment-of-inertia variation as 
                         the satellite has great decrease in size and weight. This is the 
                         case for a microsatellite with mass less than 100 kg where the ACS 
                         performance and robustness become very sensitive to both kinds of 
                         uncertainties. As a result, the design of the SAC has to deal with 
                         both types of uncertainties which is associated with the drawback 
                         between controller performance and robustness. The purpose of this 
                         work is to model a microsatellite taking into account the 
                         uncertainties and to perform the Control System Design based on 
                         the mixed H-2/H-infinity methodology via LMI optimization.",
