  • Further discussion on impulse energy approximation 

    Lucas, T. Nigel (Institute of Electrical and Electronics Engineers, 1987-02)
    Recent criticisms by Rao about impulse energy approximation are answered in detail. Further ideas are put forward as to how weighted energy parameters may be used to determine the reduced models for step inputs.
  • Least-squares Pade reduction: a nonuniqueness property 

    Lucas, T. Nigel; Smith, I. D. (Institution of Engineering and Technology, 1995-09)
    It is shown that least-squares Pade reduced order models are not unique for a given order. Depending on which reduced denominator coefficient is chosen to be unity. The method is seen to minimise an error index over different ...
  • Scaled impulse energy approximation for model reduction 

    Lucas, T. Nigel (Institute of Electrical and Electronics Engineers, 1988-08)
    It is shown that the impulse energy approximation technique for model reduction can be improved by scaling in the frequency domain. The method remains simple to use and retains the stability property of impulse energy ...
