Nonlinear Observers and Applications
This book basically gathers the material of the 28th Grenoble International Summer School on Control, dedicated to ”Nonlinear observers and appli- tions”, organized within the Control Systems Department (former Laboratoire d’AutomatiquedeGrenoble)ofthenewlyformedGIPSA-labresearchcenter,and hosted by the ”Maison Jean Kuntzmann” of the IMAG Institute, in September 2007. The motivation for this school and the present book is twofold: on the one hand, the observer problem is undoubtedly crucial in control systems, and on the other hand there are not so many comprehensive documents on this topic. Thepresentonedoesnotclaimto be exhaustive,but cangivea goodideaonthe problem, on the possible tools to get solutions, and on various applications. Its spiritbasicallyfollows fromthe pioneeringstudies which took placein particular in Grenoble in the early eighties, and the subsequent developments, owing a lot to Guy Bornard and his coworkers. In particular, a general overview on observer tools for nonlinear systems is here proposed, focuses on high gain and adaptivegain techniques aregiven, aswell asimmersion and optimization-based approaches. Some applications in control and fault or parameter estimation are ?nally discussed. I am grateful to all the contributors for their participation in this project.
