Recently\, high precision positioning techniques have become widely used in several applications related to semiconductors\, biomedical scien ce\, optics\, haptics\, and microscopy. For example\, theoretical work in molecular manufacturing has highlighted the need for very small (a fractio n of a nanometer) and very accurate manipulators\, which simultaneously ha ve a wide range of motion\, thus permitting the flexible assembly of molec ular components. This\, in turn\, requires a dramatic improvement in two i nterrelated robotic components\, namely\, actuators and controllers. Conve ntional robotic technology is already close to the limit of its performanc e ability\, and it is difficult to expect an essential improvement in term s of accuracy and dynamic response by using the traditional actuators such as DC motors and controllers. The new level of performance can be achieve d by used new smart materials such as piezoelectric and magnetostrictive a ctuators. Piezoelectric actuators can perform sub-nanometer moves at high frequencies because they derive their motion from solid-sate crystalline e ffects. Indeed\, such manipulators driven by piezoelectric actuators have been commercially available\, which allows us to find reliable and practic al control solutions that enable the manipulators to achieve high speed an d position accuracy over a wide environment range. Because the piezoelectr ic actuators are serving as manipulator’s actuators\, the available cont rol schemes for the conventional robotic manipulators need to be re-invest igated. Specifically\, the new real-world control schemes need to consider different nonlinearities of these actuators. Non-smooth nonlinearities of ten severely limit system performance and affect the accuracy. An importan t example is piezoelectric actuators\, which are finding many new applicat ions in areas demanding high precision under different conditions. The maj or limitation of piezoelectric actuators\, however\, is limited accuracy d ue to different nonlinearities. This motivates to conduct the fundamental research related to control of general dynamic micro -and nano-positioning systems involving nonsmooth nonlinearities. Important examples include hy steresis\, backlash\, and creep. These nonlinearities are very common in n ew industrial control systems\, ranging from high technology applications such as micromanipulation in semiconductor manufacturing to traditional ap plications\, which include electro-hydraulic positioning systems and robot manipulators. The presentation focuses on real-time solutions to enhance the performance of smart micro/nano-positioning systems with high nonlinea rities in real-time systems.\n\nCo-sponsored by: IEEE Montreal Section\, P ower Electronics Society Chapter \n\nSpeaker(s): <p><strong>Dr. Mohammad A l Janaideh</strong></p>\, \n\nAgenda: \nRefreshments will be served.\n\nRo om: MC603\, Bldg: McConnell Engineering Building\, 3480 Rue University\, M ontreal\, Quebec\, Canada\, H3A 0E9 LOCATION:Room: MC603\, Bldg: McConnell Engineering Building\, 3480 Rue Univ ersity\, Montreal\, Quebec\, Canada\, H3A 0E9 ORGANIZER:n.hashemia@ieee.org SEQUENCE:25 SUMMARY:Precision Motion Control for Smart Micro/Nano-Positioning Systems w ith High Nonlinearities URL;VALUE=URI:https://events.vtools.ieee.org/m/168320 X-ALT-DESC:Description: <br /><p><span style="font-size: 18pt\;"><strong><s pan style="color: #0000ff\;">M</span><span style="color: #ff6600\;">E</spa n><span style="color: #339966\;">T</span>i<span style="color: #ff0000\;">S </span></strong> Talk Series</span></p>\n<p align="justify"><span style="f ont-size: 12pt\;">The global research in the areas of micro-robotics\, hig h-precision control\, and modern mechatronic systems is expanding.
