Abstract :
A binary distillation column modelled by nonlinear differential equations is controlled by means of a state feedback and feedforward control law that eliminates the effect of disturbances on the process output. The control scheme needs a state vector observer so, an asymptotic state observer is included in the control structure. The results obtained in simulation are shown.
