Tuning fractional order proportional integral controllers for fractional order systems
Journal of Process Control, 2010Abstract 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, 2009In 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, 2014In 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.

On Fractional-Order QFT Controllers
Journal of Dynamic Systems, Measurement, and Control, 2006We propose the synthesis of robust fractional-order controllers using the principles of quantitative feedback theory (QFT). The resulting controllers are called as fractional-order QFT controllers. To demonstrate the synthesis method, we synthesize proportional-integral-derivative (PID) and more general types of fractional-order QFT controllers for a ...

Fractional order self-tuning control
2015 IEEE 13th International Conference on Industrial Informatics (INDIN), 2015This paper presents an innovative design method of polynomial control laws by mean of pole placement which are actually smart solutions to many industrial applications. Even if this category of controllers is very popular in industry, most of their applications concern problems of constant reference signals.

Fractional order control - A tutorial
2009 American Control Conference, 2009Many real dynamic systems are better characterized using a non-integer order dynamic model based on fractional calculus or, differentiation or integration of non-integer order. Traditional calculus is based on integer order differentiation and integration.

Fractional-Order Control: General Aspects
2020The 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), 2013This 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.
