Designing of Fractional Order PID Controller for Unstable Fractional Order System

2019 Joint International Conference on Digital Arts, Media and Technology with ECTI Northern Section Conference on Electrical, Electronics, Computer and Telecommunications Engineering (ECTI DAMT-NCON), 2019
This paper proposes the fractional-order proportional-integral-derivative (FOPID or $\mathbf { P } \mathbf { I } ^ { \lambda } \mathbf { D } ^ { \mu }$) controller design optimization for a stable fractional order (FO) system by using the flower pollination algorithm (FPA), one of the most efficient metaheuristic optimization search techniques.

Event-Triggered Fractional-Order PID Control of Fractional-Order Networked Control System

2021
This work focuses on the design of a fractional-order PID (FOPID) controller for output stabilization of a fractional-order networked control system (FONCS). It is widely discussed that the real systems are fractional in nature and can be better modelled in terms of fractional order.

IMC based Fractional order PID controller

2011 IEEE International Conference on Industrial Technology, 2011
This article presents the design of Internal Model Controller (IMC) based Fractional Order Two-Degrees-of-Freedom controller with the desired bandwidth specification and the robustness of the designed controller is briefly analyzed. For the conventional IMC based PID controller, One-Degree of Freedom is sufficient to meet the desired bandwidth ...

Fractional order PID controller (FOPID)-Toolbox

2013 European Control Conference (ECC), 2013
This paper presents a fractional order PID controller (FOPID)-Toolbox to design robust fractional PID controllers achieving a desired crossover frequency and a desired phase margin. A novel approach based on nonsmooth optimization techniques is used. Two types of controllers are considered, the (PID)n and PIαDβ controllers.

Fractional order controller based on the fractionalization of PID controller

2017 5th International Conference on Electrical Engineering - Boumerdes (ICEE-B), 2017
In this paper, a design method of fractional order controller using a new technique called “fractionalization” of PID controller has been proposed. This method uses a classical PID controller in a unity feedback control system where the PID controller parameters have been already adjusted using any classical method; then the PID controller is ...

Development of neural fractional order PID controller with emulator

ISA Transactions, 2020
This paper focuses on tuning parameters of fractional order PID controller (FOPID) by using neural networks (NNs). For tuning the coefficients of the controller and orders of fractional derivative and integrator, five exclusive NNs are employed. Moreover, an emulator is used to identify the plant's behavior.

Fractional-order IMC-PID controller design for fractional-order time delay processes

2020 28th Iranian Conference on Electrical Engineering (ICEE), 2020
This paper presents an analytical IMC based fractional-order PID controller tuning approach for fractional-order processes with time delay. The conventional IMC scheme utilizing first order filter suffers from the inability to reject the input disturbances of integrating processes. To tackle this issue, a new three-degree-of-freedom IMC scheme equipped

Variable-, fractional-order discrete PID controllers

2012 17th International Conference on Methods & Models in Automation & Robotics (MMAR), 2012
The fractional calculus is the area of mathematics that handles derivatives and integrals of any arbitrary order (fractional or integer, real or complex order) [1,2,3,4]. Nowadays it is applied in almost all areas of science and engineering. Here one can mention its numerous and successful applications in dynamical systems modeling and control with ...
