This brief introduces a new fractional-order integral derivative () controller for a class of
integrating systems involving time delays. The stability region is explored through the …

This paper investigates a repositioned inner-loop stabilized internal model control technique
for demanding inverse response industrial processes and bioreactors with …

A dual-degree of freedom (dual-DOF) propor-tional-integral proportional-derivative (PI-PD)
controller is developed for integrating-type chemical processes with delay. The interior-loop …

The demeanour of many chemical and non-chemical processes resemble that of an
integrating process. Develo** a control plan for an integrating process is complicated, and …

The paper proposes a modified IMC-based Smith predictor (SP) control method for unstable
time-delay processes. A novel design method to tune the parameters of a fractional-order tilt …

In current studies, non-integer order (NIO) plants with dead time have gained the significant
attention of many researchers in the area of control theory. However, the design methods for …

This article proposes an enhanced control of integrating cascade processes. The
importance of the scheme shows by controlling a double integrating process with time delay …

To achieve good servo and regulatory responses, a generalized fractional-order tilt-integral-
derivative (FOTID) control is developed in this study for time-delayed fractional-order …
