Chaos Control in Fractional Order Smart Grid with Adaptive Sliding Mode Control and Genetically Optimized PID Control and Its FPGA Implementation

open access: yesComplexity, 2017
We investigate a specific smart grid system and its nonlinear properties. Lyapunov exponents are derived to prove the existence of chaos and bifurcation and bicoherence contours are investigated to show the parameter dependence and existence of quadratic

Fractional-order feedback control of a poorly damped system [PDF]

open access: yes, 2014
This study presents the design of a fractional-order proportional-integral (FOPI) controller for a mass-spring-damper system which is poorly damped. A model based design technique is used to design a FOPI controller for this system. A good performance of

Robust Stabilization of Fractional-Order Systems with Interval Uncertainties via Fractional-Order Controllers

open access: yesAdvances in Difference Equations, 2010
We propose a fractional-order controller to stabilize unstable fractional-order open-loop systems with interval uncertainty whereas one does not need to change the poles of the closed-loop system in the proposed method.

Fractional-Order Adaptive Backstepping Control of a Noncommensurate Fractional-Order Ferroresonance System [PDF]

open access: yesMathematical Problems in Engineering, 2018
In this paper, fractional calculus is applied to establish a novel fractional-order ferroresonance model with fractional-order magnetizing inductance and capacitance. Some basic dynamic behaviors of this fractional-order ferroresonance system are investigated.

Consensus Tracking of Fractional‐Order Multiagent Systems via Fractional‐Order Iterative Learning Control [PDF]

open access: yesComplexity, 2019
In this work, the consensus problem of fractional‐order multiagent systems with the general linear model of fixed topology is studied. Both distributed PDα‐type and Dα‐type fractional‐order iterative learning control (FOILC) algorithms are proposed. Here, a virtual leader is introduced to generate the desired trajectory, fixed communication topology is
