Synchronous reluctance motor operating point dependent parameter determination

An operating-point-dependent approach to the modeling of a synchronous reluctance motor is considered. The Fock and Hart testing method is used to obtain the motor parameter values x/sub d/, x/sub q/, and r for different values of input voltage magnitude and frequency. From the accumulated points, a three-dimensional surface for each parameter is generated, and a function is formulated to describe the surface. As a result of this modeling technique, an input-variant, nonlinear model of the motor is obtained, such that a nonlinear control technique can be applied for a more precise control strategy.<>
