CIM applications in fractional domain: Fractional-order universal filter & fractional-order oscillator

AEU - International Journal of Electronics and Communications, 2022
In this work, applications of current inverting metamutator (CIM) are explored in fractional domain for the very first time. The realization of a current-mode universal fractional-order filter (FOF) and a sinusoidal fractional-order oscillator (FOO) circuit utilizing one CIM block is presented.

Variable Order Fractional Controllers

Asian Journal of Control, 2012
AbstractThis paper addresses variable order fractional controllers. Four situations where variable order fractional controllers may be used to cope with time‐varying plants are used as examples. In all cases a constant phase margin is sought, thus resulting in a constant overshoot in step responses, which is otherwise unattainable.

Fractional-order ADRC framework for fractional-order parallel systems

2020 39th Chinese Control Conference (CCC), 2020
This study discusses the control of parallel fractional order systems (FOSs) by the fractional-order active disturbance rejection control (FOADRC) technique. The FOADRC framework for linear FOSs and the necessary conditions for the existence of a stable controller of the system are given.

Fractional‐order iterative learning control for fractional‐order linear systems

Asian Journal of Control, 2011
AbstractIn this paper, we discuss in time domain the convergence of the iterative process for fractional‐order systems. Fractional order iterative learning updating schemes are considered. For the linear time invariant (LTI) system case, the convergence conditions of the fractional‐order and integer‐order iterative learning schemes are proved to be ...

Fractional Order Universal Adaptive Stabilizer for Fractional Order Systems

Volume 4: 7th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B and C, 2009
In this paper, the fractional order universal adaptive stabilization of fractional order SISO system is discussed. The fractional universal adaptive stabilizer is u(t) = −k(t)sgn{CB}y(t), where 0Dtβk(t) = ‖y(t)‖p, which guarantees the asymptotic stability of the equilibrium point of fractional order state space system with finite control effort ...
