Abstract :
The structured singular value framework is applied to a distillation benchmark problem formulated for the 1991 IEEE Conference on decision and control (CDC). A two degree of freedom controller, which satisfies all control objectives of the CDC problem, is designed using μ-synthesis. The design methodology is presented and special attention is paid to the approximation of given control objectives into frequency domain weights
