Grid-Connected Inverter Based on a Resonance-Free Fractional-Order LCL Filter
Fractal and Fractional, 2022 The integer-order LCL (IOLCL) filter has excellent high-frequency harmonic attenuation capability but suffers from resonance, which causes system instability in grid-connected inverter applications. This paper studied a class of resonance-free fractional-

Approximated Fractional Order Chebyshev Lowpass Filters [PDF]
Mathematical Problems in Engineering, 2015 We propose the use of nonlinear least squares optimization to approximate the passband ripple characteristics of traditional Chebyshev lowpass filters with fractional order steps in the stopband. MATLAB simulations of(1+α),(2+α), and(3+α)order lowpass filters with fractional steps fromα = 0.1 toα = 0.9 are given as examples. SPICE simulations of 1.2, 1.

Approximating Ideal Filters by Systems of Fractional Order [PDF]
Computational and Mathematical Methods in Medicine, 2012 The contributions in this paper are in two folds. On the one hand, we propose a general approach for approximating ideal filters based on fractional calculus from the point of view of systems of fractional order. On the other hand, we suggest that the Paley and Wiener criterion might not be a necessary condition for designing physically realizable ...

Fuzzy Adaptive Command-Filter Control of Incommensurate Fractional-Order Nonlinear Systems
Entropy, 2023 This paper focuses on the command-filter control of nonstrict-feedback incommensurate fractional-order systems. We utilized fuzzy systems to approximate nonlinear systems, and designed an adaptive update law to estimate the approximation errors.
