Three-dimensional trajectory tracking of a hybrid autonomous underwater vehicle in the presence of underwater current
TL;DR: A six degrees-of-freedom nonlinear kinematic and dynamic model of a Hybrid Autonomous Underwater Vehicle (H-AUV) is derived for the two modes of locomotion, propelled and gliding modes to ensure minimal trajectory tracking error and energy consumption.

Recursive and symbolic calculation of the elastodynamic model of flexible parallel robots
Sébastien Briot,Wisama Khalil +1 more
TL;DR: The generalized Newton–Euler model is used and combined with the principle of virtual powers to minimize the number of operators and intermediate variables to compute the elastodynamic model of a prototype of a planar parallel robot developed at IRCCyN: the DualEMPS.

Active vibration control of smart hull structure using piezoelectric composite actuators
TL;DR: In this article, the active vibration control performance of the smart hull structure with macro-fiber composite (MFC) is evaluated and a linear quadratic Gaussian (LQG) control algorithm is designed in order to effectively and actively control the imposed vibration.

Experimental analysis of the dynamic, mechanical behaviour of a chicken egg
TL;DR: In this paper, the dynamic, mechanical behaviour of a chicken egg is assessed and modal analysis tests revealed several spherical modes in the 2-7 kHz frequency band. But the authors did not identify the mode shapes, resonant frequencies and corresponding damping ratios of these modes.

Analysis and numerical modelling of eddy current damper for vibration problems
TL;DR: In this article, a new inverse method to numerically determine the dynamic properties of the contactless eddy current damper is proposed, based on a lineal viscous force.
