Modeling of Piezoelectric-Actuated Nanopositioning Stages Involving with the Hysteresis, nonlinear part of the general model are identified, respectively. For the linear part, an axiomatic-design-theory-based approach is adopted to identify the linear plant. For the nonlinear part, a particle swarm optimization algorithm is utilized for identification of the MPI model on basis of the i

Control Issues of MEMS Nanopositioning Devices,trothermal actuator has a dynamic range of 14.4 μm and the electrothermal sensor has a low drift of 8.9 nm over 2000 s. An open-loop controller is first designed and implemented. It is experimentally shown that uncertainties result in unacceptable positioning performance. Hence, feedback control is

Nanopositioning for Lithography and Data Storage,evices and materials at a nanoscale. Nanopositioners are precision mechatronic systems applied to move objects over a small range with a resolution down to a fraction of an atomic diameter. Hence, nanopositioners need to possess high resolution, accuracy, stability, and fast response. To realize man
