摘要： In the present invention, nonlinear functions between magnetic flux and current of a synchronous motor are prepared. Moreover, axis-error estimation calculation expressions, where magnetic-flux saturation characteristic is taken into consideration, are derived from these nonlinear functions via expression modification. Then, these calculation expressions derived are executed. This process makes it possible to provide a control apparatus for allowing the position/speed sensorless control to be implemented merely by setting several parameters with respect to the synchronous motor as well. Here, in the synchronous motor, the magnetic-flux saturation is conspicuous, and there exist large number of inter-axes cross-coupling magnetic fluxes.

摘要： A method of estimating a rotor angle of a synchronous reluctance motor, where the motor comprises a stator and a rotor. First, a stator flux and a stator current are determined. Two orthogonal stator flux components in a stator reference frame are calculated from the stator flux. Two orthogonal stator current components in the stator reference frame are calculated from the stator current. A rotor orientation vector is then calculated using a known rotor direct or quadrature axis inductance component, the stator flux components, and the stator current components. The rotor orientation is estimated on the basis of the rotor orientation vector.
