Trajectory optimization in terms of quasi-velocity vector

Proceedings of the 45th IEEE Conference on Decision and Control, 2006
This paper deals with optimization of unnormalized quasi-velocities (UQV) introduced originally by Jain and Rodriguez (1995). The UQV are based on a decomposition of the manipulator mass matrix. The optimization is based on the Pontryagin maximum principle.

A new digital algorithm for the velocity translation vector

Science China Information Sciences, 2013
The error of the conventional sculling correction algorithm under maneuvers is analyzed through Taylor series expansion; a generalized error equation is presented. Using frequency-series sculling algorithms in the digital algorithm for the velocity translation vector will cause the accuracy of the digital algorithm under maneuvers to decrease by one ...

P-Vector Spirals and Determination of Absolute Velocities

Journal of Oceanography, 2000
A simple method to invert the absolute geostrophic velocity on potential-density surfaces is developed based on McDougall’s (1988) conservation statements on potential-density surfaces and Chu’s (1995) and McDougall’s (1995) P-vector concept. This method has a capability to handle a system with diapycnal velocities and non-coincidence of potential ...

The Discovery of the Vector Representation of Moments and Angular Velocity

Archive for History of Exact Sciences, 2002
The author studies the discovery of vector representation of moments and angular velocity. In this deep study chapters are devoted to: Frisi and the parallelogram of infinitesimal rotation (1759); Euler and the vector representation of moments of forces (1780); Laplace and the invariable plane (1798); Prony and the diffusion of Euler's formula (1800 ...
