A comprehensive review of modified Internal Model Control (IMC) structures and their filters for unstable processes

A Ranjan, U Mehta, S Saxena - Annual Reviews in Control, 2023 - Elsevier
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 …

Fractional-order tilt integral derivative controller design using IMC scheme for unstable time-delay processes

A Ranjan, U Mehta - Journal of Control, Automation and Electrical …, 2023 - Springer
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 …

Practical application of fractional-order PID controller based on evolutionary optimization approach for a magnetic levitation system

S Dey, S Banerjee, J Dey - IETE Journal of Research, 2023 - Taylor & Francis
This article proposes a state-of-the-art design procedure of integer-order PID (IOPID) and
fractional-order PID (FOPID) controller applied to a well-established and diversified …

[PDF][PDF] FRACTIONAL CONTROLLER TECHNIQUES FOR UNSTABLE AND INTEGRATING PLANTS WITH TIME DELAY

A Ranjan - 2023 - researchgate.net
Stable type models are easier to manage in the process sector than unstable and integrated
type models. Given these processes, the control also has to be quick to reject disturbances …
