Abstract
Two design techniques that ensure the stability of linear multivariable systems for high feedback gains are introduced. The first one copes with non-square systems and presents a squaring-down method which guarantees that all the root-loci of the system will stay at the left half-plane for high values of the feedback gain. The second technique achieves the same objective for the square case by means of linear state feedback or by its equivalent dynamic feedback scheme. Both methods guarantee stability, irrespective of the original system structure.Keywords
