Abstract :
By applying known operator theoretic tools for the minimisation of the weighted H∞ norm of sensitivity, explicit closed form expressions involving Blaschke products are obtained for fundamental limits on the output feedback control of linear multivariable systems. These depend on both the right-hand plane poles and zeros, and their relative alignments
