A fibre optic based ranging sensor
… which is split and transmitted along two unequal paths before being recombined to form a beat signal. The frequency of this beat signal varies proportionally with the path difference. Incoherent light, from a 780 nm modulated laser diode, was launched into a fibre optic Michelson interferometer …

Control for transient response of turbocharged engines
… in this thesis to identify and verify possible air-path enhancements. A systematic method for evaluating various turbocharger assistance concepts is proposed and discussed in this thesis. To ensure a fair comparison of selected candidate systems, an easily reconfigurable controller providing a …

Ultrasonic Continuous Wave Spirometer
… travelling in opposite directions along the air path. The information about the transit times is contained in the phase differencces of the two sound waves across the path. A phase-locked loop is used to keep the differences across the parth constant, irrespective of air - and sound - …

On Modeling and Nonlinear Model Reduction in Automotive Systems
… reduction case study is performed on an engine air path. The heuristic method commonly used when modeling engine dynamics is compared with a more systematic approach based on the balanced truncation method.The main contribution of this thesis is a method for model reduction of nonlinear systems. …

Applicability of hybrid methods in engine control system design
… in a diesel engine test cell. A control relevant air-path model was developed using experimental work carried out on a diesel engine and dynamometer, with the aim of improving the engine control during the transients required by aftertreatment devices. This was considered as a two input and two …
