LTI modelling of active magnetic bearings by means of system identification
(SAIEE Publications, 2011)
A relatively unknown phenomenon in active magnetic bearings (AMBs) is that the frequency content of their rotor position signal can induce nonlinear behaviour in the bearings. The existence of such frequency-induced nonlinear ...
State space model extraction of thermohydraulic systems Part II: a linear graph approach applied to a Brayton cycle–based power conversion unit
(ELSEVIER, 2013)
This second paper in a two part series presents the application of a developed state space model
extraction methodology applied to a Brayton cycle-based PCU (power conversion unit) of a PBMR (pebble
bed modular reactor). ...
Optimal power control of a three-shaft brayton cycle based power conversion unit
(Gardenview [South Africa] : SAIEE Publications, 2010)
Object-oriented embedded C
(IEEE, 2009)
This paper presents an object-oriented implementation of ANSI-C for embedded systems.
It offers practical guidelines for producing generic software libraries and portable applications. While
various object-oriented ...
Multiple frequency fault detection, correction and identification of vibration forces on the rotor of a rotational active magnetic bearing system
(School of Electrical, Electronic and Computer Engineering, North-West University, 2009)
A two-dimensional analytic thermal model for a high-speed PMSM magnet
(IEEE, 2015)
Permanent-magnet synchronous machines
(PMSMs) are well suited for high-speed (HS) applications
due to their high efficiency, power density, and dynamic
response capability. The heat extraction area decreases as
the ...

(ELSEVIER, 2013)
This second paper in a two part series presents the application of a developed state space model

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 ...
Multivariable H? or Centre of gravity PD control for an active magnetic bearing flywheel system
(SAIEE Publications, 2011)
A state-space model with uncertainties for an active magnetic bearing energy storage flywheel system (Fly-UPS) is developed. A multivariable robust H? controller for the Fly-UPS is then synthesised. Different weighting ...
