Adaptive sliding mode control with perturbation estimation and PID sliding surface for motion tracking of a piezo-driven micromanipulator / Yangmin, Li. in IEEE Transactions on control systems technology, Vol. 18 N° 4 (Juillet 2010) 

Public ISBD [article]  in IEEE Transactions on control systems technology > Vol. 18 N° 4 (Juillet 2010) . - pp. 798-810 Titre : Adaptive sliding mode control with perturbation estimation and PID sliding surface for motion tracking of a piezo-driven micromanipulator Type de document : texte imprimé Auteurs : Yangmin, Li., Auteur ; Qingsong Xu, Auteur Année de publication : 2011 Article en page(s) : pp. 798-810 Note générale : Génie Aérospatial Langues : Anglais (eng) Mots-clés : Flexure  mechanism  Hysteresis  Micromanipulator  Nonlinear  system  Piezoelectric  actuation  Robust  control Index. décimale : 629.1 Résumé : This paper proposes an improved sliding mode control with perturbation estimation (SMCPE) featuring a PID-type sliding surface and adaptive gains for the motion tracking control of a micromanipulator system with piezoelectric actuation. One advantage of the proposed controller lies in that its implementation only requires the online estimation of perturbation and control gains without acquiring the knowledge of bounds on system uncertainties. The dynamic model of the system with Bouc-Wen hysteresis is established and identified through particle swarm optimization (PSO) approach, and the controller is designed based on Lyapunov stability analysis. A high-gain observer is adopted to estimate the full state from the only measurable position information. Experimental results demonstrate that the performance of proposed controller is superior to that of conventional SMCPE in both set-point regulation and motion tracking control. Moreover, a submicron accuracy tracking and contouring is achieved by the micromanipulator with dominant hysteresis compensated for a low magnitude level, which validates the feasibility of the proposed controller in the field of micro/nano scale manipulation as well.

Dahl model-based hysteresis compensation and precise positioning control of an XY parallel micromanipulator with piezoelectric actuation / Qingsong Xu in Transactions of the ASME . Journal of dynamic systems, measurement, and control, Vol. 132 N° 4 (Juillet 2010)

Titre : Dahl model-based hysteresis compensation and precise positioning control of an XY parallel micromanipulator with piezoelectric actuation Type de document : texte imprimé Auteurs : Qingsong Xu, Auteur ; Yangmin, LI., Auteur Année de publication : 2010 Article en page(s) : 12 p. Note générale : Systèmes dynamiques Langues : Anglais (eng) Mots-clés : Feedback  Feedforward  Hysteresis  Micromanipulators  Particle  swarm  optimisation  Piezoelectric  actuators  Position  control  Three-term  control Index. décimale : 629.8 Résumé : This paper presents a new control scheme for the hysteresis compensation and precise positioning of a piezoelectrically actuated micromanipulator. The scheme employs an inverse Dahl model-based feedforward in combination with a repetitive proportional-integral-derivative feedback control algorithm along with an antiwindup strategy. The dynamic model of the system with Dahl hysteresis is established and identified through particle swarm optimization approach. The necessity of using global optimization and how to choose the model parameters to be optimized are addressed as well. The effectiveness of the proposed controller is demonstrated by several experimental studies on an XY parallel micromanipulator. Experimental results reveal that both antiwindup and repetitive control strategies can improve the positioning accuracy of the system, and a well performance of the proposed scheme for both one-dimensional tracking and two-dimensional contouring tasks of the micromanipulator is achieved. Moreover, due to a simple structure, the proposed methodology can be easily generalized to other micro- or nanomanipulators with piezoelectric actuation as well.
