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 ...
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 ...
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 ...
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 ...
Alcohol and the oculomotor neural circuit: system identification, a delay-based approach
(IEEE, 2015)
A fair amount of research has been done on the
modeling of the oculomotor system. Models of the oculomotor
neural circuitry that include the effect of alcohol are less plentiful
in literature. We investigated the ...
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 ...
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 ...
