Variable-order fuzzy fractional PID controller

ISA Transactions, 2015
In this paper, a new tuning method of variable-order fractional fuzzy PID controller (VOFFLC) is proposed for a class of fractional-order and integer-order control plants. Fuzzy logic control (FLC) could easily deal with parameter variations of control system, but the fractional-order parameters are unable to change through this way and it has confined

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.

Control Fractional-Order Continuous Chaotic System via a Simple Fractional-Order Controller

Applied Mechanics and Materials, 2013
A universal fractional-order controller is proposed to asymptotically stable the unstable equilibrium points and the nonequilibrium points of continuous fractional-order chaos systems. The simple fractional-order controller is obtained based on the stability theorem of nonlinear fractional-order systems.

UBIQUITOUS FRACTIONAL ORDER CONTROLS?

IFAC Proceedings Volumes, 2006
Abstract There is an increasing interest in dynamic systems and controls of noninteger orders or fractional orders. Clearly, for closed-loop control systems, there are four situations. They are 1) IO (integer order) plant with IO controller; 2) IO plant with FO (fractional order) controller; 3) FO plant with IO controller and 4) FO plant with FO ...

The effect of the fractional-order controller's orders variation on the fractional-order control systems

Proceedings. International Conference on Machine Learning and Cybernetics, 2003
This paper concerns fractional-order controllers. The definitions and properties of fractional calculus are introduced. The mathematical descriptions of the fractional-order system and the fractional-order controller are outlined. The variation of the fractional-order controller's order and its effect on the fractional-order control systems are ...

Tuning fractional order proportional integral controllers for fractional order systems

Journal of Process Control, 2010
Abstract In this paper, two fractional order proportional integral controllers are proposed and designed for a class of fractional order systems. For fair comparison, the proposed fractional order proportional integral (FOPI), fractional order [proportional integral] (FO[PI]) and the traditional integer order PID (IOPID) controllers are all designed ...

Tuning fractional order proportional integral controllers for fractional order systems

2009 Chinese Control and Decision Conference, 2009
In this paper, two fractional order proportional integral controllers are designed to improve the performance and robustness for a class of fractional order systems which can better model many real systems such as bioengineering systems. For comparison between the fractional order proportional integral controllers and the traditional integer order PID (

Fractional order extremum seeking control

22nd Mediterranean Conference on Control and Automation, 2014
In this paper, we propose a new control scheme based on Extremum-Seeking (ES) combined with Fractional-Order Systems (FOS). This auto-tuning strategy involving a fractional order integral action, is developed to optimize the system response without external dithering, exploiting disturbances already present in the control system.
