In this paper, the position control of linear induction motor using fuzzy sliding mode integral controller design is proposed. First, the indirect field oriented control LIM is derived. Then, a designed sliding mode integral control (SMIC) system with an integral-operation switching surface is investigated, in which a simple adaptive algorithm is utilized for generalized soft-switching parameter. Finally, a fuzzy sliding mode controller is derived to compensate the uncertainties which occur in the control, in which the fuzzy logic system is used to dynamically control parameter settings of the SMIC control law. The effectiveness of the proposed control scheme is verified by numerical simulation. The numerical validation results of the proposed scheme have presented good performances compared to the conventional sliding mode controller.
