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.

Fractional-Order Control: General Aspects

2020
The chapter presents the basic principles of fractional calculus and its application to the design and tuning of controllers for generic position and velocity systems. The complete tuning procedures for fractional-order PI/PD/PID controllers are presented, as well as some worked-out examples.

An adaptive fractional-order controller

Proceedings of the 14th International Carpathian Control Conference (ICCC), 2013
This paper deals with a possible adaptation algorithm for the fractional order controllers. Suggested adaptation is based on the heuristic principle, where the controller gain and the fractional order could be adapted. The fractional order controller is presented in discrete form together with implementation algorithm.
