Abstract : Frequently it is desirable in system control problems to find poles of transfer functions of the form (G(s) e to the power ( tau s))/(1 + G(s) e to the power ( tau s)) where G(s) is either the ratio of unfactored polynomials or the ratio of linear and quadratic factors in either rootlocus or Bode form. A FORTRAN IV digital computer program has been written by the author to find these poles. This paper describes the usage of this routine. Test cases are given showing sample input and output.
