A self–sensing active magnetic bearing based on a direct current measurement approach
Active magnetic bearings (AMBs) have become a key technology in various industrial applications. Self-sensing AMBs provide an integrated sensorless solution for position estimation, consolidating the sensing and actuating ...
CREAK descriptor evaluation for visual odometry
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 ...
State space model extraction of thermohydraulic systems Part II: a linear graph approach applied to a Brayton cycle–based power conversion unit
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)
Self-sensing for electromagnetic actuators. Part 1: A coupled reluctance network model approach
A self-sensing arrangement in active magnetic bearings (AMBs) comprises a single electromagnetic transducer to realize the actuation and sensing functions concurrently. Minimizing the number of sensing devices and associated ...
An integrated self-sensing approach for active magnetic bearings
(SAIEE Publications, 2011)
Self-sensing permits active magnetic bearings (AMBs) to consolidate the actuation and sensing functions into a single electromagnetic transducer. Eliminating the position sensing device as well as interfacing reduce potential ...
Self-sensing for electromagnetic actuators. Part 2: Position estimation
The second paper in a two part series presents the position estimation scheme for an 8-pole heteropolar active magnetic bearing (AMB). The integrated self-sensing assembly comprises a nonlinear MIMO parameter estimator ...
Object-oriented embedded C
(School of Electrical, Electronic and Computer Engineering, North-West University, South Africa, 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)
Fault diagnosis of generation IV nuclear HTGR components – Part 1. The error enthalpy-entropy graph approach
Fault diagnosis (FD) is an important element in modern nuclear power plant (NPP) diagnostic systems. In this respect, FD of generation II and III water-cooled nuclear energy systems has become an active research topic to ...
