SYNCHRONOUS RELUCTANCE MOTOR OPERATING POINT DEPENDENT PARAMETER DETERMINATION

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(d), x(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.
