Techniques for decoupling, commonly applied in distillation control, have not gained recognition in all areas of process control. This is illustrated by investigating an example from the literature that presents the design of a multivariable controller for an industrial solid-fuel boiler. The suggested decoupling controller can be improved by the use of simplified decoupling valid for all frequencies using well-known methods. However, the existing methods for simplified decoupling of 2 x 2 systems cannot always be applied because of realizability issues. To solve this problem, a modification to simplified decoupling approaches is introduced.
