Abstract Superior controllability of reactive distillation (RD) systems, designed at the maximum driving force (design‐control solution) is demonstrated in this article. Binary or multielement single or double feed RD systems are considered. Reactive phase equilibrium data, needed for driving force ...

Proportional-integral-derivative (PID) control is widely practised as the base layer controller in the industry due to its robustness and design simplicity. However, a supervisory control layer over the base layer, namely a model predictive controller (MPC), is becoming increasingly popular with the...

Abstract This paper describes the currently available techniques for root‐cause diagnosis of plantwide oscillation and future directions for research in this area. Plantwide oscillation arises mainly for three reasons: (1) tight controller tuning, (2) loop interactions and (3) presence of nonlinear ...

Valve stiction is a hidden menace in process control loops. The presence of stiction in control valves limits the control loop performance. Compensation of its effect is beneficial before the sticky valve can be sent for maintenance. This work is the first of a two part study on control valve sticti...
