  • Use of spectral kurtosis for improving signal to noise ratio of acoustic emission signal from defective bearings 
    Ruiz Cárcel, Cristóbal; Hernani-Ros, E.; Cao, Yi; Mba, David (Springer Verlag, 2014-03)
    The use of Acoustic Emission (AE) to monitor the condition of roller bearings in rotating machinery is growing in popularity. This investigation is centred on the application of Spectral Kurtosis (SK) as a denoising tool ...
  • Using Coriolis Mass Flowmeter for Wet Gas Metering 
    Geng, Y. F.; Yeung, Hoi; Cao, Yi; Xing, L. C.; Zhu, H.; Drahm, W. (Institute of Measurement & Control, 2010-07-31)
    Established wet gas metering techniques are typically based on differential pressure devices, and their measurement accuracy is still unsatisfactory to natural gas industry. Coriolis mass flowmeter (CMF) is the most ...
  • Variable sampling-time nonlinear model predictive control of satellites using magneto-torquers 
    Cao, Yi; Chen, Wen-Hua (Taylor & Francis, 2014-09-30)
    Satellite control using magneto-torquers represents a control challenge combined with strong nonlinearity, variable dynamics and partial controllability. An automatic differentiation-based nonlinear model predictive control ...
  • Venturi multiphase flow measurement based active slug control 
    Nnabuife, Somtochukwu Godfrey; Whidborne, James F.; Liyun Lao, Liyun; Cao, Yi (IEEE, 2019-11-11)
    Riser slug flow poses a significant challenge to offshore oil production systems, most especially for oil fields in their later life. Active control of slugging through choking has been proven a practical approach in ...
