Summary:A sensorless control strategy for switched reluctance motor (SRM) drive based on an improved simplified flux linkage model method is proposed in this paper. Instead of searching look-up tables to take offline data of flux linkage, this paper uses polynomials to fit only the flux linkage of commutation position. Simulation is carried out in detail) and the feasibility of this theme is demonstrated. Experiments are also conducted to verify the simulation results by using a 6/4-pole prototype SRM as a research subject and the dSPACE as the controller. The simulation and experimental results are fairly consistent and the rotor position can be well estimated without position sensor.
