This article presents a new cascaded control strategy to the power flow in renewable-energy-based microgrid operating grid-connected mode. The model is composed of an AC utility grid interfaced with multi-functional interactive converter (MF-GIC) acting as grid-forming converter, photovoltaic (PV) power-generation system grid-feeding distributed generation unit, and various sensitive/non-sensit...

This paper applies fractional order PID controller to torsional system’s backlash vibration suppression control, in which the order k of D controller can not only be integer but also be any real number. In order to improve control system’s robustness against backlash non-linearity, several methods have been proposed. However their design processes are very complicated. In this paper, a clear an...

This paper presents a toolbox developed in Matlab for analysis and design of fractional order control systems that can be used in advanced control courses within the context of master and doctorate education. The toolbox includes a user friendly interface for every function. One can obtain time and frequency analysis tools both for the fractional order control systems and fractional order contr...

This paper is concerned with an uncertainty and disturbance estimator-based tracking control problem for a class of interval type-2 fractional-order Takagi-Sugeno fuzzy systems subject to time-varying delays. The footprints the underlying are taken into account capture model different levels uncertainties. estimator used promote behavior rejecting in system. First, by applying Lyapunov approach...

This paper describes the simple Internet tool for fractional order pole models the Java applet free accessible on www.PIDlab.com. The applet implements procedures described in the authors’ previous works, where the value set approach to fractional order pole systems was presented for the case, when following characteristic numbers of the process were obtained: a) one sample of the process frequ...
