Adaptive control schemes based on characteristic model for …
This paper proposes two novel adaptive control schemes for servo motor drives based on CM method. By establishing the CM in terms of discrete difference, a novel adaptive controller which consists of four control laws is designed. The maintaining/tracking control law is improved by using a torque ripple observer.

Distillation Column Control | SpringerLink
The modelling of a distillation column can be performed at different complexity levels with regard to the objective. Models called rigorous (Skogestad 1992, 1997) concern models which include the mass and energy balances at each stage, a dynamic model of the liquid flow and a model of the pressure dynamics, possibly a model of the reboiler and the condenser.
