The function [bound,muinfo,RSmargin]=fRS(M,om) computes the robust stability margins for the uncertain plant M and for the frequency grid \omega=[\omega_1,\ldots,\omega_N]. It returns the \mu-ssv upper- and lower-bounds by means of the mussv command from the Robust Control Toolbox. The outputs are:

  • bound: A structure with the lower- and upper-bounds for each frequency \omega\in[\omega_1,\ldots,\omega_N].
  • muinfo: The \mu-information obtained during the computations.
  • RSmargin: The robust stability margins.
