ABSTRACT:
Disclosed is a method for controlling an SRM (Switched Reluctance Motor) switching angle by an analog encoder system that can perform a precise control of the switching angle of the SRM by comparing an analog sensor signal detected by the analog encoder system with a switching-on/off command signal. During a rotation of an encoder rotor having rotary slits formed at the same intervals on the encoder rotor and continuous contrast patterns formed between the respective rotary slits, analog sensor signals θato θddetected in proportion to the contrast patterns are compared with a switching-on/off command signal controlled by a digital-to-analog (D/A) converter. A switching-on angle θonis set to a crossing point of the switching-on command signal Vonand a slope between the sensor signals θaand θo, and a switching-off angle θoffis set to a crossing point of the switching-off command signal Voffand a slope between the sensor signals θoand θd.
