Relative Gain Array (RGA)

The Relative Gain Array (RGA) is a classical widely-used[citation needed] method for determining the best input-output pairings for multivariable process control systems. It has many practical open-loop and closed-loop control applications and is relevant to analyzing many fundamental steady-state closed-loop system properties such as stability and robustness.

I cover how you can find the relative gain array from the steady state gain array, and interpret the results to determine which input to pair with which outp...
