Abstract :
In this paper, we consider a case study for which multivariable control achieves better performance than decentralized control due to plant interactions and bandwidth limitations. We analyze the structure of the multivariable controller by introducing an "equivalent controller" that achieves the same performance, but is more amenable to simplification. We then show analytically that the multivariable controller must necessarily have the structure of the one that was designed.
