Abstract
This study presents a novel fractional-order nonlinear sliding mode controller (FONSMC) based on an extended nonlinear disturbanceobserver(ENDOB)foraclassoffractionalordersystemswithmatchedandmismatcheddisturbances.Firstly,an ENDOBisintroducedtoestimateboththematchedandmismatcheddisturbances.Then,thefractional-ordernonlinearsliding surfaceisdesignedtosatisfytheslidingconditioninfinitetime.Accordingly,thecorrespondingFONSMCisproposedusing the Lyapunov stability theorem. The proposed method shows an impressive disturbances rejection and also guarantees finitetimestabilityofclosed-loopsystems.Finally,theeffectivenessoftheproposedFONSMC-ENDOBstructureisillustratedvia numerical simulation. The simulation results exhibit the superiority of the proposed controlling method.
