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 …

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 …

This paper deals with high-order unstable systems, which are dangerous and more difficult
to control. Their presence is increasingly prevalent, posing a great challenge to both …

In this paper, generalized predictive control strategy is applied for unstable time delay series
cascade processes. The control structure consists of a secondary loop with a secondary …

To control unstable and stable plants a new series cascade control structure (SCCS) is
proposed. The proposed SCCS incorporates two or three controllers (setpoint tracking …

An IMC-PID controller was proposed for unstable second-order time delay system which
shows the characteristics of inverse response (RHP zero). A plot of M s versus λ was …

This article emphasizes the implementation of a control strategy for time-delayed series
cascade processes with unstable poles. A cascade control scheme encompasses an inner …

In this study, an approach to tune the Proportional Integral Derivative (PID) controller has
been proposed to achieve enhance regulatory response. The proposed approach depend …

In process industries, cascade control is comprehensively used for disturbance attenuation.
This manuscript presents the control of the non-minimum phase (NMP) system with dead …

The primary intent of this article is to explicate the development of an efficient control
strategy to enhance the automated drug infusion technique and thereby, regulating the …
