Variable-order fuzzy fractional PID controller
ISA Transactions, 2015In this paper, a new tuning method of variable-order fractional fuzzy PID controller (VOFFLC) is proposed for a class of fractional-order and integer-order control plants. Fuzzy logic control (FLC) could easily deal with parameter variations of control system, but the fractional-order parameters are unable to change through this way and it has confined

IEEE Control Systems Letters, 2020
This letter proposes a fractional order internal model controller (FO-IMC) for a fractional order plus time delay (FrOPTD) process model to satisfy desired gain margin ( $A_{m}$ ) and phase margin ( $\phi _{m}$ ) specifications.

Variable Order Fractional Controllers
Asian Journal of Control, 2012AbstractThis 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.

Level control of a conical tank using the fractional order controller
Computers & electrical engineering, 2020This work proposes a fractional-order internal model controller (FOIMC), for the height control of a conical tank nonlinear system. The proposed controller has a fractional filter cascaded with an integer-order PID controller.

Fractional‐order iterative learning control for fractional‐order linear systems
Asian Journal of Control, 2011AbstractIn 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 inverse filters revisited: Equivalence with fractional-order controllers
Microelectronics Journal, 2023The equivalence of fractional-order inverse filters with fractional-order controllers is demonstrated in this work. This is achieved by appropriately rewriting the filters transfer functions in order to clarify the correspondence between the gain and time-constant of the filters and the scaling factor and differentiation/integration constant of the ...
