“…The model is numerically invertible, which makes it convenient to use. If desired, it could be expressed as inductance functions in a manner similar to (8) and (9). The algebraic model (12) was further simplified by using only selected integers as exponents.…”

This paper proposes a standstill method for identification of the magnetic model of synchronous reluctance motors (SyRMs). The saturation and cross-saturation effects are properly taken into account. The motor is fed by an inverter with a short sequence of bipolar voltage pulses that are first applied on the rotor d-and q-axes separately and then simultaneously on both the axes. The stator flux linkages are computed by integrating the induced voltages. Using the current and flux samples, the parameters of an algebraic magnetic model are estimated by means of linear least squares. The proposed method is robust against errors in the stator resistance and inverter voltage, due to the high test voltages (of the order of the rated voltage). The fitted model matches very well with the reference saturation characteristics, measured using a constant-speed method, and enables extrapolation outside the sample range. The method was tested with a 2.2-kW SyRM, whose shaft was uncoupled from any mechanical load, which is the most demanding condition for this method. The proposed method can be used for automatic self-commissioning of sensorless SyRM drives at standstill.

“…The works presented in [20], [21], [22], [23], [24], [25], [26], [27], [28], [29] fall under the first category of offline identification methods using a power converter. Machine magnetic model identification test setup from [22] and the obtained current-to-flux-linkage curves are shown in Fig.…”

Parameter identification of permanent magnet synchronous machines is a topic of utmost interest these days. The growing effort and investment in this field of research is largely due to the ever-expanding market share of these machines. The high-performance and efficient control of the drive depends on the accuracy with which the information about the machine connected to its terminals is available. The available identification methods are surveyed here and they are classified into offline and online strategies. Self-commissioning, in principle, is a subset of offline methods, yet it is treated separately for its importance in modern adjustable speed drives that tend to minimize the user intervention. Fully exploiting the power electronic converter and the computational power on-board a modern drive, the self-commissioning feature can be embedded in the start-up routine of the drive to estimate the parameters of the machine at hand. This paper presents a review of the parameter identification techniques and schemes investigated over the past few decades.

“…The wound rotor has higher inductance in the d-axis then the q-axis Lsd > Lsq (In the d-axis, the salient pole iron of the rotor has higher magnetic conductivity than the air gap in the q-axis), therefore the positive d-axis current has to be used for the reluctance utilization for the increasing of the total moment. As the surface permanent magnet synchronous motors (PMSMs) are controlled [3], [4], [5] the first idea how to optimally operate these wound motor is to keep the d-axis stator current to be zero up to the base speed, but it usually was not common even thirty years ago [6], [7], [8], [9]. The most utilized strategy is to orient the vector control on stator or magnetic flux linkage, where the field rotor current is higher than nominal and the d-axis stator current is negative.…”
