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 ...
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 ...
Variance-based sensitivity of localized sulphation to microporous separator properties using a distributed parameter model of a valve-regulated lead-acid battery
(Electrochemical Society, 2016)
Progressive sulphation of the negative electrode in a lead-acid battery under high-rate operation remains a serious problem. This study investigates how healthier end-of-discharge conditions, in a valve-regulated lead-acid ...
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. ...
Data acquisition system for capturing dynamic transients in a control valve
(IEEE, 2004)
This work presents the development of a data acquisition (DAQ) system to be used in conjunction with fuzzy modelling to derive a dynamic mathematical model of a control valve. Characterising the behaviour of a control valve ...
Action evolution for intelligent agents
(IEEE, 2005)
This paper introduces an alternative method of reinforcement learning for intelligent agents. The aim with this method is to closer emulate the natural thought processes of problem solving. This paper only provides a ...
Energy-based visualisation of a counter-flow heat exchanger for the purpose of fault identification
(Elsevier, 2016)
The need for fault detection and diagnosis (FDD) is becoming increasingly important for industrial processes as the complexity of processes increases. A state space model of a counter-flow heat exchanger is used study to ...
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 ...
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 ...
