In recent years, the complexity of CubeSat missions has been increasing steadily as the
platform capabilities have drastically improved. Missions involving high-accuracy pointing …

In this paper a result on attitude control of a microsatellite by integrator backstepping based
on quaternion feedback is presented, and the controller is shown to make the closed loop …

This paper presents a new approach to vibration reduction of flexible spacecraft during
attitude maneuver by using the theory of variable structure control (VSC) to design switching …

A nonlinear energy sink (NES) approach is proposed for whole-spacecraft vibration
reduction. Frequency sweeping tests are conducted on a scaled whole-spacecraft structure …

Tracking of triangular or sawtooth waveforms is a major difficulty for achieving high-speed
operation in many scanning applications such as scanning probe microscopy. Such non …

Through unique folding methods and material selection, origami structures enable optimum
structural design within a restricted space and provide strong force support. In aerospace …

In this paper, a piezoelectric tube of the type typically used in scanning tunneling
microscopes (STMs) and atomic force microscopes (AFMs) is considered. Actuation of this …

This paper is devoted to the attitude and vibration control of spacecraft containing flexible
appendages. It entails an investigation of a passive control strategy which consists in …

The dynamic analysis on the ultra-large spatial structure can be simplified drastically by
ignoring the flexibility and damping of the structure. However, these simplifications will result …

Falling particle receivers are being evaluated as an alternative to conventional fluid-based
solar receivers to enable higher temperatures and higher efficiency power cycles with direct …
