英文摘要: |
The conduction phase inductance of switched reluctance motor will change with the change of the conduction phase current
under the case of magnetic circuit saturation, resulting in a low rotor position estimation accuracy. Aiming at this problem, a position
sensorless control method of switched reluctance motor considering magnetic circuit saturation is proposed. Firstly, the relationship
formula of the phase inductance function is established, and then the relationship between the phase current and the position angle of the
extreme positioning point of the phase inductance is analyzed. Finally, the realization process of estimating the corresponding rotor
position angle from the two adjacent extreme positioning points is described. Finally, the related simulation and experiment were carried
out with a three-phase 6 / 4 structure motor. The results show the feasibility of the above method. |
