Dynamic Performance of Dual-PM Partitioned-primary Hybrid-excited Flux-switching Linear Machine

To overcome the demerits of conventional hybrid-excited flux-switching linear machine (HEFSLM), a novel dual-PM partitioned-primary HEFSLM (dual-PM PP-HEFSLM) has been proposed and investigated with merits of high thrust force density, improved space utilization, flexible flux control and robust secondary. To this novel dual-PM PP-HEFSLM, this paper investigates its dynamic performance with a primary-flux-oriented (PFO) vector control strategy. Firstly, the d-q mathematical model of the proposed machine has been derived. Then, the proposed PFO vector control strategy is presented in detail. Finally, the proposed control schemes are validated through MATLAB/Simulink simulation. The simulation results shows that the proposed machine exhibits good dynamic performance by adoption of the PFO vector control strategy.
