  • Attitude control system for directional drilling bottom hole assemblies 
    Panchal, Neilkunal; Bayliss, Martin T.; Whidborne, James F. (Iet, 2012-05-31)
    A general approach for the attitude control of directional drilling tools for the oil and gas industry is proposed. The attitude is represented by a unit vector, thus the non-linearities introduced by Euler angle ...
  • Bilinear modelling and bilinear PI control of directional drilling 
    Inyang, Isonguyo J.; Whidborne, James F.; Bayliss, Martin T. (IEEE, 2016-11-10)
    This paper presents the design of an inclination- and azimuth-hold controllers and their subsequent stability and performance analysis for directional drilling tools as typically used in the oil industry. Using an input ...
  • Directional drilling attitude control with input disturbances and feedback delay 
    Inyang, Isonguyo J.; Whidborne, James F.; Bayliss, Martin T. (Elsevier, 2017-10-18)
    This paper presents a general approach for the attitude control of directional drilling tools for the oil and gas industry. It extends the recent work where a kinematic bilinear model of the directional drilling tool was ...
  • Modelling and control of the roll-stabilised control unit of a rotary steerable system directional drilling tool 
    Alturbeh, Hamid; Whidborne, James F.; Luk, Patrick Chi-Kwong; Bayliss, Martin T. (IET, 2019-04-26)
    A directional drilling tool control unit whose design is based on servo control of a rotary valve using the roll-stabilised instrumented system approach has been successfully used in oil fields for over 20 years. Here, ...
  • The numerical modelling of elastomers 
    Bayliss, Martin T. (Cranfield UniversitySchool of Engineering, 2003)
    This thesis reports onreview and research work carried out on the numerical analysis of elastomers. The two numerical techniques investigated for this purpose are the finite and boundary element methods. The finite element ...
  • Numerical modelling of elastomers using the boundary element method 
    Bayliss, Martin T.; El-Zafrany, A. (Wiley, 2004-08-18)
    The FEM analysis of hyper elastic, elastomeric materials has been formulated and implemented for various material models (strain energy functions) over the years. More recently, the analysis of elastomeric materials has ...
