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 ...
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 ...
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 ...
Pseudo-magnetic centre identification of an active magnetic bearing for sensorless drive control start-up
(Elsevier, 2017)
A method of identifying runout of an active magnetic bearing at standstill and low speed is presented. The on-line current bias injection method found in literature is improved, but is still found to converge too slowly ...
Using visual texture analysis to classify raw coal components
(IEEE, 2015)
Coal ore isn’t a uniform material. In order to
optimize the coal liberation process it is necessary to classify
a coal ore sample into its constituent components as quickly
and cheaply possible. This paper investigates ...
A survey on reducing reconfiguration cost: reconfigurable PID control as a special case
(IFAC, 2014)
Reconfigurable computing is a paradigm in computing architecture that refers to the
practice of using interchangeable hardware modules to enhance the performance of conventional
Von-Neumann style computing. Despite the ...
Monitoring gearbox oil viscosity by means of motor current signal analysis
(Univ of Huddersfield, 2017)
A number of gearbox failures can be attributed to lubricant related problems. One
measure of the condition of gearbox oil is its viscosity. In electrically powered systems,
motor current signal analysis allows online ...
Active surface area approximation in a lead-acid cell for optimal performance in renewable energy systems
(IFAC, 2014)
In a renewable energy system, lead-acid batteries are required to last as long as possible whilst
providing deep discharges and are usually charged in an intermittent manner. This type of operation is
severely detrimental ...
Control of magnetically suspended rotor combined with motor drive system
(IFAC, 2014)
This paper presents the cooperative control between the active magnetic bearing
system and the permanent magnet synchronous drive. More specifically, the coupling between
the vibration control and sensorless drive control ...
Automatic infarct planimetry by means of swarm-based clustering
(PRASA, 2014)
Infarct planimetry is an important tool in cardiology
research. At present this technique entails that infarct size
is manually determined from scanned images of prepared heart
sections. Existing attempts at automating ...
