The real-time optimization (RTO) system of distillation column has been proposed using sliding modes. On the basis of formulated optimization problem, the parameters for the distillate composition controller are so selected that the condition for the occurrence of sliding modes holds in order to provide a search procedure. An investigation of the transient performance of RTO-system under feed composition disturbances indicated a stable tracking for the shifted optimal distillation operating points.
