“…In [12], an algorithm based on polynomial approximation was proposed to compensate every possible input rotor position. In [13], an adaptive method was proposed to compensate for the speed-dependent position estimation offset. In addition, some methods employed in sensorless control, such as rotating injection [14], pulsating injection [15] and high-frequency signal injection [16], can also be used to calibrate the position offset.…”

In high-performance field-oriented control of permanent magnet synchronous machines (PMSMs), an accurate rotor position is indispensable for the key roles in coordinate transformations. However, due to the rotor position offset error and the time delay in digital control systems, it is still challenging to obtain exact rotor position information. In this study, the influence of rotor position error on the control performance of a PMSM drive system is analysed first. Then, two novel compensation technologies, i d regulation and i q = 0 methods, are proposed to accurately compensate for the rotor position for both current and voltage coordinate transformations. The advantage of the proposed scheme is that even without any prior knowledge of the system delay, the rotor position offset and compensation time coefficients can also be precisely calculated. Parameter sensitivity analysis is carried out, and compensation criteria are also provided to improve the compensation accuracy. Experimental results on a 300 kW PMSM drive system demonstrate that compared to the results achieved with conventional methods, the compensation accuracies of the phase angles used for the current and voltage coordinate transformations are increased by 6°a nd 3.1° at 5000 r/min, respectively. Consequently, the control performance and stability margin of the system are efficiently improved.

“…In line with improving the economic efficiency of PMSM production and exploitation is the advancement of sensorless control approaches for the PMSM that are based on rotor position estimation using observers that are usually based on machine models expressed in the fixed stator reference frame (Xiong, 2021;Popovici, 2019;Andersson, 2018;Han, 2016;Morimoto, 2002;Corley, 1998). Although the states of the model in the stator reference frame vary with the rotor position, they have the advantage to contain quantities that can be determined directly, without knowledge of the rotor position, i.e., the applied phase voltages and measured phase currents.…”

The paper presents the deduction of a novel decoupled form (considering the differential current quantities) of the differential mathematical model in stator reference frame, useful for numeric simulation of control approaches for PMSM (permanent magnet synchronous machines) generalized for both IPMSM and SPMSM (salient and non-salient PMSM). The model is confirmed to be equivalent to the well-known model defined in the rotor synchronous reference frame using a Matlab-Simulink implementation that is verified and validated by simulation during which the power/energy conservation is monitored and the system states’ evolution is compared to the reference model in rotor reference frame using a generator structure.
