An operating point dependent approach toward the modeling of the 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 3-D 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.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
