Definitions for positive-and negative-coupled multivariable plants are presented. A theorem stating the condition for the structural monotonic instability of linear multivariable interacting control systems with positive-coupled plants and integrating controllers has been proved. The application of this condition to the input/output pairing problem has been illustrated.
