Rotor-Position Estimation of Switched Reluctance Motors Based on Damped Voltage Resonance
2010
IEEE transactions on industrial electronics (1982. Print)
This paper proposes a method to obtain the rotor position of switched reluctance motors by means of voltage measurements. It is shown that the combination of motor and power-electronic converter defines a resonant circuit, comprised by the motor phase inductances and the parasitic capacitance of converter switches, power cables and motor phase windings. For salient machines in general, the associated resonance frequency of the circuit depends on the rotor position. In the position estimation
