DESCRIPTION:I will present in this talk some of my work (before joining Ca
 mbridge) on the robustness analysis of interconnected systems. More precis
 ely\,  I will talk about the problem of robust performance analysis of int
 erconnected uncertain systems with a hierarchical structure. The computati
 onal load associated with such problems does not allow a direct applicatio
 n of robustness analysis usual tools. To overcome this difficulty\, we exp
 loit the hierarchical structure of the problem and propose an algorithm to
  perform robustness analysis using dissipativity property (quadratic const
 raint) “propagation” along the hierarchical structure. This algorithm 
 allows to establish a trade-off between computation time required to perfo
 rm the analysis and the conservatism of the obtained results. Furthermore\
 , it is possible to perform parallel computation at each hierarchical leve
 l using the proposed algorithm which will result in an important decrease 
 in the required computation time.
