SUMMARY:A Network-Optimization Framework for Cooperative Control of Passive
 -Short Systems
DESCRIPTION:Lecturer:Miel Sharf\n Faculty:Department of Aerospace Engineeri
 ng\n Institute:Technion – Israel Institute of Technology\n Location:Clas
 sroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstract: \
 n Details: \n The mathematical theory of nonlinear cooperative control re
 lies heavily on notions from graph theory and passivity theory. A general
  analysis result is known about cooperative control of maximally equilibr
 ium-independent passive systems\, relating steady-states of the closed-lo
 op system to optimal solutions of certain static convex network optimizati
 on problems. This relation has many applications in various areas of mult
 i-agent systems\, e.g. model-free control\, network identification\, and 
 fault detection and isolation.\nHowever\, when trying to apply the framewo
 rk to passive-short systems directly\, it fails\, as the cost function in 
 the optimization problem becomes non-convex\, or even undefined. We show t
 he network optimization framework can be extended to output-passive short 
 systems by regularizing the said optimization problems\, inducing a passiv
 izing feedback term on the agents. We explore two methods of doing so. We 
 then study systems with general shortage of passivity\, showing that a pas
 sivizing transformation can always be found by an analogous regularization
  process. We exemplify our results by case studies.
