N2 - The fast response of linear speed for linear induction motors (LIMs) based on sliding mode control with finite-control-set model predictive flux control is proposed in this paper. In this proposed method, the linear speed is controlled using the sliding mode control (SMC) instead of the proportional-integral (PI) control. Besides, the finite-control-set (FCS) depends on the primary flux only, hence the weighting factor is eliminated. Furthermore, the calculation processes reduce as the primary flux is only required in the prediction stage. The proposed control method is applied to guarantee lower thrust ripples. All variables and states for estimation, prediction, and cost function are in the αβ-coordinates. During the modeling of the LIMs and the proposed control process, the end-effect is taken into consideration. The proposed SMC with the FCS-MPC is compared with the PI with the FCS-MPC under variable linear speed and load thrust variation. The proposed SMC with FCS-MPC can achieve a faster dynamic response over PI. A 3kW setup of the arc induction machine is used to verify the performance of the proposed control strategy.
