In recent decades, MIMO (Multi-Input-Multi-Output) systems become more and more widely used inindustrial applications. A variety of decoupling control algorithms have been studied in the literature. Therefore,a review of the most extensively applied coupling interaction analysis and decoupler design methods for industrialprocesses is necessary to be carried out. In this paper, in order to benefit researchers and engineers with differentacademic backgrounds, the scattered coupling interaction analysis and decoupling algorithms are collectedand divided into different categories with their characteristics, application domains and informative comments forselection. Moveover, some frequently concerned problems of decoupling control are also discussed.
