Position estimation at starting and lower speeds in three-phase switched reluctance machines |
| 摘要 |
Provided is a method of indirect position estimation in three-phase switched reluctance machines. The method may comprise providing a three-phase switched reluctance machine. A three-phase switched reluctance machine may comprise a rotor and three phases. The method may further comprise producing data about the machine, setting threshold current values for at least a first phase; and sensing rotor position. Sensing rotor position may comprise applying a sensing pulse voltage sufficient to induce a pulse current having some maximum amperage in the first phase, determining the amplitude of the maximum amperage of said pulse current with respect to the thresholds for the first phase, and determining the sector of the rotor based upon the amplitude of the maximum amperage of the pulse current in the first phase. |

1. A method of indirect position estimation in three-phase switched reluctance machines comprising:
providing a three-phase switched reluctance machine, said machine comprising a rotor and three phases; producing data about the machine; setting a plurality of threshold current values for at least a first phase; and sensing rotor position by; applying a pulse voltage train sufficient to induce a pulse current in said first phase, said pulse current having some maximum amperage amplitude, comparing the maximum amperage amplitude of said pulse current to at least one of the plurality of threshold current values for the first phase, and determining the sector of the rotor based upon the maximum amperage amplitude of the pulse current in the first phase. |
