Adaptive sliding-mode control of piezoelectric actuators / Sunan, Huang in IEEE transactions on industrial electronics, Vol. 56 N° 9 (Septembre 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N° 9 (Septembre 2009) . - pp. 3514-3522 Titre : Adaptive sliding-mode control of piezoelectric actuators Type de document : texte imprimé Auteurs : Sunan, Huang, Auteur ; Tan, Kok Kiong, Auteur ; Lee, Tong Heng, Auteur Article en page(s) : pp. 3514-3522 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Adaptive  sliding-mode  control  Piezoelectric  actuators Index. décimale : 621 Ingénierie mécanique en général. Technologie nucléaire. Ingénierie électrique. Machinerie Résumé : In this paper, we consider the adaptive control problem for piezoelectric actuators with nonlinear uncertainties. The controller consists of two parts: sliding mode and adaptive component. The sliding-mode part rejects dominant uncertainties, while the adaptive component is continuously refined based on just prevailing input and output signals. The stability of the designed control system can be guaranteed by a rigorous proof. Simulation and real-time experimental results are provided to verify the effectiveness of the proposed scheme.

Vision-servo system for automated cell injection / Zhang, Yi in IEEE transactions on industrial electronics, Vol. 56 N°1 (Janvier 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N°1 (Janvier 2009) . - pp. 231 - 238 Titre : Vision-servo system for automated cell injection Type de document : texte imprimé Auteurs : Zhang, Yi, Auteur ; Tan, Kok Kiong, Auteur ; Sunan, Huang, Auteur Année de publication : 2009 Article en page(s) : pp. 231 - 238 Note générale : electronics Langues : Anglais (eng) Mots-clés : biological  techniques;  computer  vision;  medical  control  systems;  microactuators;  micromanipulators;  servomechanisms Résumé : Recent developments in nuclear reprogramming and intracytoplasmic sperm injection reflect an increasing need for more advanced and automatic micromanipulation technologies. In this paper, we present an automatic cell injection system, which is capable of visually monitoring the injecting process and controlling the microactuators. Traditionally, cell injection was manually operated, and it was laborious, time consuming, of low accuracy, and prone to contamination due to the handling requirements. An automatic and efficient strategy is required to eliminate these drawbacks. In this paper, a system is developed where the injection process is monitored and controlled automatically via integration of a vision system to an injector manipulation system. The cell is located, and the pipette is positioned and driven by the algorithm to achieve effective penetration. The precision achieved is physically proven to be within a good tolerance range.
