In this paper a practical procedure is proposed for the decoupling design of multivariable feedback systems. The so-called V-canonical compensator is used to remove the need for inversion of the plant transfer function matrix. The cross-coupling in the plant is first expressed in terms of the equivalent disturbance. Then a strictly-decoupling formula is established to reduce this equivalent disturbance. Ultimately, nearly-decoupling control is concerned with the design of a realizable compensator.

In this paper, a practical approach is introduced for the design of multivariable feedback systems. At first, the cross-coupling in the plant is expressed in terms of the equivalent disturbance. The ''non-interacting'' formula is then established to remove the effects of the equivalent disturbance on the designing compensator. Ultimately, ''nearly non-interacting control'' is concerned from the viewpoints of engineering. A typical two-degree-of-freedom system structure is adopted to handle the conflict between the command-tracking performance and the disturbance-rejection requirement.
