N2 - In this paper, the multi-segmented PMLSM mathematics model of dual inverters power supply strategy is established through the profound research on the changing rules of inductance and coupling flux linkage, based on the mechanical and electromagnetic structural characteristics of the motor. Meanwhile, according to the model, the thesis puts forward the novel combined direct thrust control (DTC) algorithm for both contiguous segment observed flux linkage and thrust, which overcome the practical difficulties of conventional DTC algorithm applied for multi-segmented PMLSM. Theoretical analysis illustrates that this algorithm not only maintains high-transient response of DTC but also minimizes inter-segment thrust ripple in segmented PMLSM. Simulation demonstrates that this controlled method presents the favorable effects of the steady and transient states even in the process of mover operations between segments.
