摘要
Exponentially converging observers for the composition profile and feed composition are presented. Their design is based, as in Lang and Gilles. on the structural properties of observability of the models of the distillation columns. Moreover, we prove the internal stability of the dynamic output feedback based on these observers and a stabilizing feedback law. Simulation results for a binary distillation column, in comparison with the linear Kalman filter, prove the efficiency of this new nonlinear estimation technique.
