Abstract
This paper presents a study of the main advantages of inverted decoupling in 2×2 processes. Two simulation examples and an experimental process are used to show these advantages in comparison with simplified decoupling. The study focuses on the following practical advantages: the apparent process is the same as that obtained if one loop changes to manual; bumpless transfer and anti-windup are achieved easily using a feed-forward input in the controllers; and abnormalities of secondary loops do not affect the opposite loop. Because of this, inverted decoupling may be a good and easy way to improve the performance of industrial TITO (two inputs and two outputs) processes with interaction problems (when it can be applied).
