New model predictive current control strategy based rotor flux for linear induction machines

In this paper, a new model predictive current control (MPCC) algorithm based rotor indirect field orientation control (FOC) strategy for linear induction machines (LIM) is proposed. This method can track the reference current very quickly without linear controllers and modulators, and it is simple enough for practical implementation. Meanwhile, one cost function is set out to optimize the converter switching sequence so as to reduce the switching frequency. Comprehensive simulations verify relevant theoretical analysis.
