Abstract

This paper describes a web-based distance experiment on the control of a two-degrees-of-freedom (DOF) monolithic piezoelectric actuator. This actuator is part of a six-DOF manipulator [1] capable of linear resolution to 2 nanometers and angular resolution to 1 arc-second [2]. The Lab VIEW/DataSocket approach has been adopted in this implementation to enhance streaming of live data as well as to facilitate the interaction among the various system modules such as PC platform, digital signal processor board, client/server interface, and the nanopositioner. Besides a LabVIEW-based client program which requires the remote PC to have LabVIEW installation, a Web browser-based client plug-in has also been generated for students/users who do not have programming experience with LabVIEW. Test results for multi-client access have been very favorable. Reliable real-time control bandwidth of the two-DOF nanopositioner was detected at about 3 KHz, adequate for undergraduate control experiments. The same client/server interface can also be applied to a wide range of experiments for 24/7 and global access.
