In this paper, the compensator based reduced order control design framework of Burns and King (J. Vibrations and control, vol. 4, pp. 297-323, 1998) is modified to yield low order systems with guaranteed stability margins. This result is achieved through use of a logarithmic barrier function. In addition, a reduced basis method is formulated in which the compensator equations are approximated on uneven grids;guaranteed stability margins are also included. The methods are tested numerically on a one dimensional, nonlinear, damped, hyperbolic structural controlproblem. Examples are provided to illustrate differences between systems designed by both reduced basis methods.
