“…(5) In this model, the magnetic flux of the permanent magnets is represented only by one component in the d-axis (term λd pm ), and it is computed by one simulation at no-load condition. Concerning the inductances, only the self-apparent inductances are taken into account and they are calculated as in (6). The magnetic flux produced by Id is considered to be the difference between the total d-axis flux and the no-load magnet flux (λd -λd pm ).…”

The classic dq model does not take into account the machine's saturation and cross magnetization. This paper presents an improved dq model and a new technique to determine the electromagnetic parameters of a PMa-SynRM under saturation condition. These parameters are computed by means of an upgraded analytical magnetic model of the motor and the Frozen Permeability Method (FPM) is applied to separate the magnetic field sources effects, keeping the same magnetic state of the steel sheets as the one at the operation point. Permanent magnet flux in both dq-axis, apparent and incremental inductances are determined and they are implemented in a complete dq model. This model is validated by means of an accurate representation of PWM harmonics in relation to a numerical model implemented in Matlab/Simulink where the motor is represented by a flux map.

“…circuit, and a method based on discrete wavelet transform is proposed. In [13], finite element analysis was used to identify the field inductance and synchronous inductance of permanent magnet synchronous motor under rated load and overload. This method obtained electrical parameter identification values by solving multiple differential equations simultaneously, which was time-consuming and inefficient.…”

Permanent Magnet Synchronous Wind Generator (PMSWG) parameter identification method with improved operator genetic algorithm is proposed for the influence of perturbations caused by mechanical parameter changes on the dynamic performance of motor speed control system. Firstly, current with i d = 0 and i d ̸ = 0 are injected into axis d respectively to design the fitness function. Through quantum coding, the genetic algorithm can obtain better population and fitness in the early stage, and find better solutions in the search space. At the same time, the cross method of two random numbers is used to make the cross variable not restricted in a range, which enhances the global search ability. Finally, the update strategy of hybrid mutation composed of Gaussian mutation and Cauchy mutation is introduced to ensure the global search ability of the algorithm, and the accuracy of the optimization results is improved. Experiments show that the proposed method avoids local optimization and achieves global optimization, which can further improve the convergence speed and identification accuracy of the algorithm.

The maximum torque per ampere (MTPA) control is significant for improving the efficiency of the interior permanent magnet synchronous motor (IPMSM). However, for the high saturation IPMSM, the change of the permanent magnet (PM) flux linkage is more complicated, which can cause the MTPA control to deviate from the optimal solution. Therefore, an improved MTPA control method for the high saturation IPMSM is proposed in this paper. Compared with other methods, the proposed method improves the conventional models of flux linkage and torque by analyzing the nonlinear variation of the PM flux linkage with the dq-axis currents. Subsequently, an expression suitable for the MTPA control of high saturated IPMSM is derived based on the improved models. The proposed parameter fitting models are then fitted using data from 11 operating points and incorporated into the MTPA optimization algorithm to obtain the MTPA curve. Finally, the effectiveness of the proposed method in enhancing the control accuracy of the MTPA angle is verified through simulations and experiments.
