End-to-end distance vector distribution with fixed end orientations for the wormlike chain model [PDF]

open access: yes, 2005
We find exact expressions for the end-to-end distance vector distribution function with fixed end orientations for the wormlike chain model. This function in Fourier-Laplace space adopts the form of infinite continued fractions, which emerges upon ...

Determinig of an object orientation in 3D space using direction cosine matrix and non-stationary Kalman filter

open access: yesArchives of Control Sciences, 2016
This paper describes a method which determines the parameters of an object orientation in 3D space. The rotation angles calculation bases on the signals fusion obtained from the inertial measurement unit (IMU).

5-Phase AC induction motor rotor flux oriented control with space vector modulation technique [PDF]

open access: yes2013 International Conference on Electrical Engineering and Software Applications, 2013
The paper deals with the analysis of the rotor flux oriented control with space vector modulation technique for a five phase induction motor drive. The speed control using the rotor flux oriented control (RFOC) with or without speed sensor uses proportional integral controlled technique which make it possible to achieve satisfactory goals on the torque

Field Oriented Control of Space Vector Modulated Multilevel Inverter fed PMSM Drive

open access: yesEnergy Procedia, 2017
Abstract In this article, field orient control (FOC) of a space vector modulated asymmetrical Multilevel inverter (MLI) fed Permanent Magnet Synchronous Motor (PMSM) is presented. The MLI considered is a reduced switch inverter which produces seven level output with six power switches and two input sources.

On duality between Cosserat elasticity and fractons

open access: yesSciPost Physics, 2020
We present a dual formulation of the Cosserat theory of elasticity. In this theory a local element of an elastic body is described in terms of local displacement and local orientation.
