    Abstract

    In this technical note, the solution to the controller reductionproblem via a double-sided frequency weighted model reduction techniqueis considered. A new method for finding low-order controllers based on newfrequency weights derived using closed-loop system approximation criterionis proposed. The formulas of frequency weights are obtained in termsof the plant, the original controller and a matrix of free parameters. Byvarying the free parameters in the resulting two-sided frequency weightedmodel reduction problem, frequency weighted error can be significantly reducedto yield more accurate low-order controllers.
