Multivariable Decoupling Control System Based on Generalized Diagonal Dominance

S. Jamebozorg; A. Shahmansoorian

In this paper, the design of static precompensator for the reduction of interaction in linear multivariable systems is proposed. In the previous studies, the diagonal dominance of systems in special frequency range has been less paid attention to. In the proposed method, some static compensators with matrix coefficients are combined so that the final static compensator can make system diagonal dominance in a wide range of frequencies. These coefficients are obtained with optimization algorithm. In this method, to achieve diagonal dominance with less conservativeness, the criterion of generalized diagonal dominance is used. The proposed method does not have any limitation for systems with high interaction or non-minimum phase systems. In comparison with some common methods, it has a simpler structure with easy implementation. Simulation examples demonstrate the usefulness of the proposed method
