DESCRIPTION:Prof. Pierre Apkarian\, ONERA and Université Paul Sabatier\nT
 his seminar will give an overview of recent non-smooth optimization techni
 ques for linear controller synthesis and tuning.\nNon-smooth techniques ha
 ve practical advantages:\n\n		They can be used to optimize arbitrary contr
 ol architectures made of single- or multiple-loop control arrangements fro
 m a collection of structured control elements including PIDs\, reduced-ord
 er state-space models\, transfer functions\, observers\, as well as custom
  controller blocks.\n	\n		They can handle multiple design requirements har
 d or soft such as  H2\, H-infinity\, margins\, pole constraints\, …\n	\
 n		They naturally lend themselves to multiple models as a way to enhance r
 obustness.\n\nThese techniques however come with a local certificate as di
 ctated by NP-hardness of the problems.\nThey can serve as good benchmarkin
 g tools for other approaches and heuristics.\nBeyond highly specialized no
 n-smooth algorithms\, a brief account of the routines HINFSTRUCT and SYSTU
 NE from the\nMATLAB Robust Control Toolbox will be presented.\nBio: Pierre
  Apkarian received the Ph.D. degree in control engineering from the Ecole 
 Nationale Supérieure de l'Aéronautique et de l'Espace (ENSAE)\,  France
 \,  in 1988. He was qualified as a Professor from Université Paul Sabati
 er (UPS) in both control engineering and applied mathematics in 1999 and 2
 001\, respectively. Since 1988\, he has been a Research Scientist at ONERA
  (Office National d'Etudes et de Recherches Aérospatiales)  and an Assoc
 iate Professor at Institut de Mathématiques\, UPS.  His research interes
 ts include robust and gain-scheduling control theory and LMI methods.  Mo
 re recently\, his research has focused on the development of specialized n
 on-smooth programming techniques for control system design. Pierre Apkaria
 n has served as an associate editor for the IEEE Transactions on Automatic
  Control and contributed to the non-smooth synthesis tools in the  Robust
  Control Toolbox of MATLAB.
