Abstract

‎In this paper‎, ‎an appropriate fractional-integer integral sliding mode method for the control of fractional-order chaotic systems with perturbations such as uncertainties and external disturbances is addressed‎. ‎When the upper bound of the perturbations is determined‎, ‎a sliding mode controller is presented‎.
‎Also‎, ‎when‎
‎the upper bound of the perturbations is unknown‎, ‎an adaptive sliding mode control is designed‎.
‎Analysis of the stability of the sliding mode surface is presented using the Lyapunov stability theory‎.
‎Eventually‎, ‎the results were carried out for the control of the complex fractional order chaotic T system‎.
