Multiwalled carbon nanotubes (MWNTs), with their excellent properties, have long been considered as a model material for realizing the potential of nanotechnology. Several techniques have been developed to tailor and manipulate MWNTs, and they have shown promise in the construction of nanobalances, nanosensors, SPM probes, nanoelectronics, fuel cells, and so on. In order to achieve their full c...

1 Corresponding Author ([email protected], 734-239-2928) ABSTRACT This paper presents the control system design and tracking performance of a large range single-axis nanopositioning system that is based on a moving magnet actuator and flexure bearing. While the physical system is designed to be free of friction and backlash, the nonlinearities in the electromagnetic actuator as well as the harmo...

This paper describes the design and manufacturing of a rigid positioning system with high resolution based on piezostepper technology. The planar piezostepper is able to move along the three in-plane directions and is able to make small correction movements in the out-of-plane directions. The piezostepper integrates the drive system, the transmission, and the bearing system into a single steppi...

There is a strong motivation for using multiple sensors for feedback control in ultrahigh accuracy data storage devices such as a probe-based data storage device. One elegant way to design such controllers using multiple sensors is to design a direct multi-input-single-output (MISO) controller using either the H2 or H∞ control design paradigm. In this paper we discuss the control of a micro-sca...
