Abstract
The paper reviews existing and presents some new results for the frequency-dependent RGA. It is shown how frequency-dependent plots of the relative gains, ¿, and the closed-loop disturbance gains, ¿, can be used to evaluate the achievable performance (controllability) of a plant under decentralized control. These controller-independent measures give constraints on the design of the individual loops.
