Research on Fault-Tolerant Operation Strategy of Permanent Magnet Synchronous Motor with Common DC Bus Open Winding Phase-Breaking Fault

open access: yesEnergies, 2022
In some key areas, fault-tolerant control is usually needed in order to enable the motor to operate continuously in fault mode. Given that it is difficult to detect the zero-sequence current of the open winding permanent magnet synchronous motor after ...

Sequences of reals to sequences of zeros and ones [PDF]

open access: yesProceedings of the American Mathematical Society, 1990
This paper considers maps from sequences of reals to sequences of zeros and ones which preserve the tail. The continuum hypothesis is used.

Sequence Subsums in Zero-Sum Theory

open access: yes, 2021
The last few years have seen the development and improvement of structural results in the area of sequence subsums over abelian groups. These results often have the flavor that either many elements can be represented as a sum of terms from  a ...

THE DEVELOPMENT OF THE THEORY OF INSTANTANEOUS POWER OF THREE-PHASE NETWORK IN TERMS OF NETWORK CENTRISM

open access: yesElectrical engineering & Electromechanics, 2017
Purpose. Information technologies allow multidimensional analysis of information about the state of the power system in a single information space in terms of providing network-centric approach to control and use of unmanned aerial vehicles as tools for ...

Zeros of recurrence sequences [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1991
We give an upper bound for the number of zeros of recurrence sequences defined over an algebraic number field in terms of their order, the degree of their field of definition and the number of prime ideal divisors of the characteristic roots of the sequence.

ASSESSMENT OF CONSUMER IMPACT ON VOLTAGE ASYMMETRY BY THE ZERO SEQUENCE AT THE POINT OF COMMON CONNECTION

open access: yesВестник Северо-Кавказского федерального университета, 2022
The article presents a technique for assessment the level of consumers’ impact on the voltage asymmetry by the zero sequence at the point of common connection. The results of a computational experiment that determine the possibility of using the level of

Linear recurrence sequences without zeros [PDF]

open access: yesCzechoslovak Mathematical Journal, 2014
There are two main results in the paper. In order to quote them we recall the following. Given a positive integer \(d\) and \(2d\) fixed integers \(a_0,\dots ,a_{d-1}\) and \(x_0,\dots ,x_{d-1}\) with nonzero \(a_0\); a linear recurrent sequence \((x_n)\) of order \(d\) is defined by these data if \[ x_{n+d}=\sum_{j=0}^{d-1}a_jx_{n+j} \] for all ...
