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 ...

An Unknown Input Nonlinear Observer Based Fractional Order PID Control of Fuel Cell Air Supply System

IEEE transactions on industry applications, 2020
Maintaining the cathode pressure stable and avoiding oxygen starvation are crucial for the air supply of proton exchange membrane fuel cell (PEMFC). In most applications, the cathode pressure and oxygen excess ratio (OER) are unmeasurable parameters ...

A fractional order PID tuning algorithm for a class of fractional order plants

IEEE International Conference Mechatronics and Automation, 2005, 2006
Fractional order dynamic model could model various real materials more adequately than integer order ones and provide a more adequate description of many actual dynamical processes. Fractional order controller is naturally suitable for these fractional order models.

Optimal Tuning of Fractional-Order PID Controller

2015
The paper proposes a comparative study of the performance of the fractional-order PID(FOPID) controller with the conventional controllers. The parameters of the FOPID controller is estimated using particle swarm optimization (PSO) algorithm, and the values are compared with the values obtained through conventional optimization techniques.

Fractional order PID system for suppressing epileptic activities

2018 IEEE International Conference on Applied System Invention (ICASI), 2018
Epilepsy is a dynamic disorder of the brain at the system level which is due to abnormal activity of the brain cells. A closed-loop control system is designed in this work to detect the epileptic seizures and hence to suppress it through stimulating the brain cells.
