This paper reviews the evolution of Internal Model Control (IMC) techniques developed so
far for unstable processes. The IMC strategy has shown significant results over the past two …

In this paper, control of stable, unstable and integrating processes with large time delay in
the presence of uncertainty, external disturbances and measurement noise is investigated …

This work combines the benefits of cascaded control, Smith predictor, moment matching,
and outer-loop decomposition to design an enhanced series cascaded control approach …

This article presents a unified approach of controller design in cascade control structure
(CCS) for unstable, integrating and stable processes with dead-time to achieve enhanced …

This paper presents a controller design method for the open-loop unstable process in the
primary loop and the open-loop unstable, integrating and stable processes in the secondary …

Many researchers have achieved satisfactory control of unstable processes using complex
control structure involving two or more PI/PID controllers. However, a simple architecture is …

This manuscript presents a modified parallel cascade control structure (PCCS) with Smith
predictor for open loop unstable and integrating process models with large time delay. The …

The fractional-order proportional-integral (FOPI) controller tuning rules based on the
fractional calculus for the parallel cascade control systems are systematically proposed in …

To control stable, unstable and integrating chemical processes, a new three-degree of
freedom (3DOF) decoupled parallel cascade control architecture (PCCA) is proposed. The …

Magnetic levitation systems (MLS) provide friction-less, dependable, quick, and affordable
operations in a variety of real life applications. One of the often-employed control strategies …
