Abstract

A design of a passive damping controller to damp first resonant mode of a piezoelectric tube scanner (PTS) used in most commercial atomic force microscopes (AFMs) for nanopositioning is proposed in this paper. The stability analysis between the proposed controller and PTS is presented by an analytical framework which examines the finite-gain stability for a positive feedback interconnection between two stable, linear time-invariant systems where one system has 'mixed' passivity, negative-imaginary and small-gain properties and the other system has 'mixed' negative-imaginary, negative-passivity, and small-gain properties. Experimental results are presented to show the effectiveness of the proposed controller.
