Abstract—Distillation is the most important separation method in the chemical and petrochemical industries. Distillation Column is highly non-linear multivariable process so it is very difficult to control such a complex process without eliminating the interactions, therefore in order to completely eliminate these interactions a Decoupler is introduced.

Index Terms—Decoupler, Distillation column, Liquid-vapor, Single-Input Single-Output (SISO), Model-Reference Adaptive Control (MRAC)
