ABSTRACT:
A method for estimating and controlling the rotor position of a SRM comprises the steps of sampling phase currents and estimating phase fluxes from at least one excited phase of the SRM, sampling phase currents and estimating phase inductances from at least one unexcited phase of the SRM, and estimating the rotor position by determining a rotor position that is common to the estimated phase flux and the estimated phase inductance solutions to predetermining flux and inductance models. The estimation of rotor position can be less sensitive to measurement noise by applying a least squares technique. Once the rotor position has been estimated by the above method, the position of the rotor can be controlled so as to provide an overall effective control of the SRM. In particular, once the position of the rotor is estimated, the excitation provided to the motor is then adjusted to urge the rotor from its current position, velocity or torque toward a desired position, velocity or torque.
