Abstract:In the SRM control，it usually needs to set an angular fine division for the positional signal of the rotor so as to fix a precise position for the rotor.This paper introduce new method of realizing angular fine division by software，simultaneously analysise the advantages and weakness of PLL(Phase-locked Loop) multiple frequency circuit to realize angular fine division.Take SRM (Switched Relucance Motor) as the control object，the two methods were used respectively，and the experimental results indicate that the angular fine division can improve the performance of SRM，but the software method is better than the hardware one in control precision and reliability.
