Tuning rules for optimal PID and fractional-order PID controllers

Journal of Process Control, 2011
Abstract In this paper we present a set of tuning rules for standard (integer-order) PID and fractional-order PID controllers. Based on a first-order-plus-dead-time model of the process, the tuning rules have been devised in order to minimise the integrated absolute error with a constraint on the maximum sensitivity.

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 ...

Discrete fractional order PID controller design for nonlinear systems

International Journal of Systems Science, 2021
In this study, a discrete fractional order PID controller for nonlinear systems is proposed. U-model is firstly employed to transform nonlinear systems into a linear-like model and model complexity is then degraded and easier for controller design. Then,

Fractional-Order PID Controllers in a Mobile Robot Control

IFAC Proceedings Volumes, 2009
Abstract In this paper fractional PID controllers are applied to the control system of a mobile robot. The short memory principle related to problems in a numerical implementation of a fractional order differ-integration is analyzed and some solutions of this problem are presented.

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 Controller for Diabetes Patients

2015
This paper proposes an optimized control policy over type one diabetes. Type one diabetes is taken into consideration as a nonlinear model (Augmented Minimal Model), which is implemented in MATLAB-SIMULINK. This Model is developed in consideration of the patient's conditions.
