• Controllability of a hovercraft model (and two general results) 

      Lewis, Andrew D.; Tyner, David R. (2003)
      Modelling and controllability studies of a hovercraft system are undertaken. The system studied is a little more complicated than some in the literature in that the inertial dynamics of the thrust fan are taken into ...
    • Jacobian linearisation in a geometric setting 

      Lewis, Andrew D.; Tyner, David R. (IEEE, 2003)
      Linearisation is a common technique in control applications, putting useful analysis and design methodologies at the disposal of the control engineer. In this paper, linearisation is studied from a differential ...
