A new input/output pairing strategy based on linear quadratic Gaussian control

摘要

In this paper a new input/output pairing strategy based on linear quadratic Gaussian control (LQG) is suggested. The strategy is used to compare the expected performance of decentralized control structures in some illustrative examples. The pairing suggestions are compared with the recommendations previously obtained using other interaction measures such as the relative gain array (RGA). The new strategy gives suitable pairing recommendations and is easy to interpret.
