Piezoelectric systems for precise and high dynamic positioning: design, modeling, estimation and control

Résumé

This HDR synthesizes the works I have carried out at the department of AS2M of the FEMTO-ST Institute as well as the different administrative, editorial and teaching activities. The research works (supervised, in collaboration, ...) deal with the: design, development, modeling, control and signals measurement and estimation in piezoelectric based systems devoted to precise and highly dynamic positioning applications. The systems behaviors include linear and nonlinear phenomena (hysteresis and creep) and badly damped vibrations which greatly compromise the performances of the positioning tasks, and which pose great challenge in their control. The proposed control techniques enclose feedforward and feedback schemes. In feedback schemes, mainly robust techniques are studied: H-infinity techniques and interval control techniques. In the use of intervals, new theoretical results are also proposed and are applied to different applications: design, control, structural analysis. Innovative measurement techniques have also been proposed to estimate the signals in piezoelectric systems by accounting for the limited space, the high dynamics and the high precision requirements. The last part of the HDR poses questions and wonders if these different developments and endeavors would not be profitable for the development of other applications than precise and highly dynamic positioning.
