Title

Observer Techniques Applied to the Control of Piezoelectric Microactuators.

Abstract

We present here the use of sensors, observers and self-sensing techniques to control piezoelectric actuators, particularly piezocantielevers. First, the feedback control with full measurements (all variables are measured) is presented. Because of the lack of convenient sensors for the microworld, non-full measurements combined with observer techniques is proposed. Finally, the self-sensing principle, where the actuator is at the same time sensor, is applied and used for the feedback.

Bio of the speakers

Micky Rakotondrabe holds the PhD degree on Automatic Control from the Université Franche-Comté in Besançon in 2006. He is currently an associate professor at the Automatic Control and MicroMechatronics Systems (AS2M) department of FEMTO-ST Institute in Besançon. He is also a permanent lecturer at the Université de Franche-Comté in Besançon. In the field of micro/nano world, his research includes the development, modeling, signal estimation and control of piezoelectric microsystems, especially accounting the nonlinearities, vibrations, and environmental disturbances.
