A fully integrated implementation of a parallel fractional-order resonator which employs together a fractional order capacitor and a fractional-order inductor is proposed in this paper. The design utilizes current-controlled Operational Transconductance Amplifiers as building blocks, designed and fabricated in AMS 0:35</mu>m CMOS process, and based on a second-order approximation of a fractional-order differentiator/ integrator magnitude optimized in the range 10Hz–700Hz. An attractive benefit of the proposed scheme is its electronic tuning capability.Citation

Fractional-order adaptive fault estimation for a class of nonlinear fractional-order systemsNdoye, Ibrahima; Laleg-Kirati, Taous-Meriem (2015 American Control Conference (ACC), Institute of Electrical and Electronics Engineers (IEEE), 2015-07-30) [Conference Paper]This paper studies the problem of fractional-order adaptive fault estimation for a class of fractional-order Lipschitz nonlinear systems using fractional-order adaptive fault observer. Sufficient conditions for the asymptotical convergence of the fractional-order state estimation error, the conventional integer-order and the fractional-order faults estimation error are derived in terms of linear matrix inequalities (LMIs) formulation by introducing a continuous frequency distributed equivalent model and using an indirect Lyapunov approach where the fractional-order α belongs to 0 < α < 1. A numerical example is given to demonstrate the validity of the proposed approach.

Robust fractional-order proportional-integral observer for synchronization of chaotic fractional-order systemsN U+02BC Doye, Ibrahima; Salama, Khaled N.; Laleg-Kirati, Taous-Meriem (IEEE/CAA Journal of Automatica Sinica, Institute of Electrical and Electronics Engineers (IEEE), 2018-02-13) [Article]In this paper, we propose a robust fractional-order proportional-integral U+0028 FOPI U+0029 observer for the synchronization of nonlinear fractional-order chaotic systems. The convergence of the observer is proved, and sufficient conditions are derived in terms of linear matrix inequalities U+0028 LMIs U+0029 approach by using an indirect Lyapunov method. The proposed U+0028 FOPI U+0029 observer is robust against Lipschitz additive nonlinear uncertainty. It is also compared to the fractional-order proportional U+0028 FOP U+0029 observer and its performance is illustrated through simulations done on the fractional-order chaotic Lorenz system.

Analysis and Verification of Identical-Order Mixed-Matrix Fractional-Order Capacitor NetworksKartci, Aslihan; Agambayev, Agamyrat; Herencsar, Norbert; Salama, Khaled N. (2018 14th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME), Institute of Electrical and Electronics Engineers (IEEE), 2018-08-17) [Conference Paper]In the open literature while capacitors are introduced with-90 degrees phase angle, here we described our fabricated polymer composite, mixed matrix, as a fractional-order capacitor (FoC). The effect on phase and pseudo-capacitance using a detailed numerical and experimental study of circuit network connections of three identical-order FoCs is shown. The used devices have excellent feature such as constant phase angle in the frequency range 200 KHz-20 MHz.
