The characterization of the severity of rotor delevitation events: a parametric study
(s.n, 2012)
Active magnetic bearing (AMB) failure and the ensuing rotor behavior is a very important
aspect of AMB safety. A model for this rotor behavior was developed and was used to
characterize the severity of rotor delevitation ...
CREAK descriptor evaluation for visual odometry
(IEEE, 2019)
Each year, latest state of the art technologies and algorithms arise that claim and prove to-shine their predecessors. One such algorithm is the Colour-based Retina Key-point (CREAK) descriptor, which is based on the FAST ...
Delevitation modelling of an active magnetic bearing supported rotor
(s.nCurran Associates, 2010)
For active magnetic bearings (AMBs) to be used with confidence in industrial applications, the safe
failure of the AMB system should be guaranteed. The exact behaviour of the rotor on the backup bearings (BBs)
is relatively ...
Heading alignment with summarized inertial pose constraints
(IEEE, 2014)
A discontinuity seems to exist in present aided
inertial navigation systems – the operational availability of high
cost inertial navigation currently depends on the availability of
a valid GPS lock. In general GPS ...
An energy perspective on modelling, supervision, and control of large-scale industrial systems: survey and framework
(IFAC, 2014)
Energy is a universal concept that can be used across physical domains to describe complex large-scale industrial systems. This brief survey and framework gives a perspective on energy as a unifying domain for system ...
A comparative study on fault detection and correction techniques on active magnetic bearing systems
(IEEE-Institute of Electrical and Electronics Engineers, 2007)
In this paper, the authors distinguish between three real-time fault detection, correction and identification schemes for vibration forces on the rotor of a rotational active magnetic bearing (AMB) system. Historical fault ...
Thermal modelling of a high speed permanent magnet synchronous machine
(IEEE, 2013)
The thermal behaviour of permanent magnet synchronous machines (PMSMs) is important since overheating of the permanent magnets can lead to demagnetization. This article gives an overview of a hybrid thermal model for a ...
Equivalent electrical circuit modelling of a Proton Exchange Membrane electrolyser based on current interruption
(IEEE, 2013)
A Proton Exchange Membrane (PEM) electrolyser is characterised and modelled to identify important electrochemical effects. These electrochemical effects include the ohmic, activation, and concentration losses within the ...
Block RAM implementation of a reconfigurable real-time PID controller
(IEEE, 2012)
Despite the numerous advantages reconfigurable computing adds to a system, it is only advantageous if the execution time exceeds the configuration time. As a result of the long configuration time, reconfiguration is only ...
Linear model of a closed three-shaft Brayton cycle
(IEEE, 2004)
A linear model of a closed three-shaft Brayton cycle is developed. The model is intended to give an understanding of the dominant dynamic behavior in a nuclear power system that utilizes a closed three-shaft Brayton cycle. ...
