Design and application of a data driven controller using the small-gain constraint for positioning control of a nano-positioner

Gupta, Tanmoy; Habibullah, H; Pota, Hemanshu R.; Petersen, Ian


In this paper, the design of a data driven controller using a small-gain theorem approach for improving the positioning accuracy of a piezoelectric tube scanner (PTS) is demonstrated. Open-loop frequency responses of both the X-PTS and Y-PTS are measured using a band-limited sweep sine signal and are used as primary data for this control design. The frequency response of the controllers is synthesized by the application of the small-gain theorem constraints over the entire frequency range for...[Show more]
