Decoupling control of a multivariable system with a desensitizer has been proposed. Interactions between control loops were decoupled by means of a desensitizer and a two-way decoupler. The objective of the desensitizer was to reduce the decoupler sensitivity while the two-way decoupler was for actually decoupling control loops. The proposed control structure was verified on models of a highly interacting system and a distillation column. The control system with desensitizer significantly enhanced the robustness of the decoupling control system.
