• Progress in airborne ultrasonic data communications for indoor applications 

  Jiang, Wentao; Wright, William M. D. (Institute of Electrical and Electronics Engineers (IEEE), 2017-01-19)

  Capacitive ultrasonic transducers are efficient transmitters and receivers for ultrasonic waves in air, making them ideal devices for signal transmissions in air. Ultrasonic signals are unregulated, difficult to intercept ...
• Distributed hierarchical droop control of boost converters in DC microgrids 

  O'Keefe, Daniel; Riverso, Stefano; Albiol-Tendillo, Laura; Lightbody, Gordon (Institute of Electrical and Electronics Engineers (IEEE), 2017-07-20)

  Voltage stability and accurate current-sharing are primary features of an efficiently operating power distribution network, such as a dc islanded-microgrid. This paper presents the development of a distributed hierarchical ...
• The effect of viscosity on the maximisation of electrical power from a wave energy converter under predictive control 

  O'Sullivan, Adrian C. M.; Lightbody, Gordon (Elsevier, 2017-07)

  In this paper, the non-linear effects of viscosity on the performance of a Wave Energy Converter (WEC) system are analysed. A standard linear Model Predictive Control (MPC) is used to show the negative effects that the ...
• The effect of model inaccuracy and move-blocking on the performance of a wave-to-wire wave energy converter , under economic predictive control 

  O'Sullivan, Adrian C. M.; Lightbody, Gordon (EWTEC, 2017-08-30)

  In this paper, an economic Model Predictive Control (MPC) is used to investigate the effects that arise from the model mismatch between the control and the system. It is shown that the average electrical power is affected ...
• Wave to wire power maximisation from a wave energy converter 

  O'Sullivan, Adrian C. M.; Lightbody, Gordon (EWTEC, 2015-09-07)

  In this paper a back-to-back voltage source converter controlled linear permanent magnet generator (LPMG) is utilised as the power take off (PTO) for a point absorber wave energy converter system (WEC). It is shown that ...
