Abstract
The widely used pairing criteria involving the Niederlinski index and the steady-state relative gain array (RGA) used for evaluating integri ty under decentralized control are extended to open-loop unstable plan ts it will in some cases be preferable to choose pairings giving negat ive Niederlinski index and/or RGA. The relationship between the two me asures is also clarified.
