Abstract

In this paper, a robust multivariable two matrix degree of freedom feedback structure is designed for an evaporator example. The evaporator is described by a 2×2 transfer matrix having uncertain time-delays and gains. The desired tracking properties of the closed loop system are a priori given, and these are to be achieved despite the large parametric uncertainty. The third MIMO quantitative feedback technique (QFT) of Horowitz is used for the design. The obtained results are verified in both frequency and time domains through simulations, and found to be acceptable over the range of uncertainty considered
