Fractional Order Tube Model Reference Adaptive Control for a Class of Fractional Order Linear Systems

International Journal of Applied Mathematics and Computer Science, 2020
We introduce a novel fractional order adaptive control design based on the tube model reference adaptive control (TMRAC) scheme for a class of fractional order linear systems. By considering an adaptive state feedback control configuration, the main idea

Indirect sliding mode adaptive fractional order nonlinear observer based controller with fractional order single-ended primary inductor converter

International Journal of Electrical Power & Energy Systems
Direct Current to Direct Current (DC/DC) converters like the SEPIC (Single-Ended Primary-Inductor Converter) use both passive and active components to control the system via a duty cycle. The SEPIC converter is non-inverting and can both step up and step

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

Advances 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.
