Abstract

The use of position sensors in switched reluctance motor drives presents disadvantages of decreased reliability and increased cost. This paper proposes a full speed range sensorless control method in order to simply address these issues. The rotor position, during running operation is estimated through a simplified model for the relationship between phase inductance for given current and rotor angle. Means of improving this model are also proposed. For position estimation at standstill, pulse injection is employed. The estimation of the phase standstill inductances is used in order to obtain the initial rotor position. The proposed method does not require a detailed knowledge of magnetic characteristics of the motor nor additional hardware. Simulation and experimental results demonstrate the satisfactory accuracy of rotor position estimation with an error of only 0.5 degrees under high load conditions.
