Abstract :
A new compensation approach for linear multivariable systems is presented. This approach is motivated by the so-called dyadic expansion. By restricting the two compensation matrices to be the real unitary matrix and the rational complex matrix, respectively, the closed-loop system will be a stable normal matrix, which enjoys the optimal H∞ norm. The effectiveness of this novel approach is verified by an example in paper-making processes.
