Robust stabilization of binary distillation columns with input constraints

This paper examines the problem of robust stabilization of binary distillation columns with input constraints. We develop a controller that takes into account the physical constraints on the inputs and which ensures the global asymptotic stability of the closed loop system, with robustness to modelling errors, and the capability of performing set point tracking and disturbance rejection. We stress that this controller does not require all the internal states to be measurable.
