摘要
This paper proposes a speed control of linear induction motor (LIM) based on a finite-set model predictive flux control (FS-MPFC). The end effect is taken into consideration for both modeling of LIM and for the proposed control method. The proposed control method is used to achieve lower thrust ripple, reduce the calculation process and eliminating the weighting factor from the cost function. The cost function is based only on the primary flux linkage error in alpha beta-coordinates. The primary flux linkage error is calculated from the difference between the reference primary flux linkage and the predicted primary flux linkage. A comparison between the proposed method and the finite set model predictive direct thrust control (FS-MPDTC) is presented to illustrate the simplicity of the proposed method. The performance of the proposed control strategy is verified by simulation results where the parameters of a 3kW platform arc induction machine is used.
