Abstract
Development of electric drive tends to the use of Switched Reluctance Motor (SRM) for their advantages and green technology issues. The SRM takes significant place in development for its simplicity, robust construction, and low cost. Sensorless method can be applied to drive SRM, it is less expansive but has more complexity and limitation. On the other hand, although sensor-based rotor position detection needs a hardware assembled on the shaft, some advantages can be obtained. In this paper, a control strategy for SRM drive with rotary encoder based rotor position detection is proposed, core of the strategy implements digital signal controller. The problem associated with wide range speed and standstill operation can be overcome by this strategy. This is also capable to vary the time to turn the switches on and off by software. The analysis was verified by simulations and experiments.
