This paper presents the development of Permanent Magnet Synchronous Motor (PMSM) control system using Hardware In the Loop System (HILS) and Look-Up Table (LUT)-based inverse flux map. The inverse flux map is developed using flux linkage calculated from Finite Element Analysis (FEA) simulation to reflect nonlinearity characteristics of an actual PMSM. In this paper, the effect of the LUT-based PMSM control system is verified by comparing the response characteristics of the control system with and without applying the developed LUT in simulation and HILS.

In this paper, magnetic properties analysis of applying grain-oriented electrical steel (GO) to the traction motors for battery electric vehicle (BEV) and hybrid electric vehicle (HEV) is conducted. For the purpose of enhancing the power characteristic of the motor, GO is applied to the stator tooth, as the magnetic flux path of the tooth part is relatively uniform at radial direction. The comparison models of each applications have the same structure and only the tooth material is changed to conduct the performance comparison under the equivalent current conditions. In particular, the specifications of the test operating points, such as speed and torque, were separately determined considering the driving characteristics of each application. A detailed analysis of the GO application effect of both models was carried out according to the current density and rotation speed, and the iron loss, torque, and efficiency at each test point were compared. Due to the narrow operating speed range and lower maximum speed of the HEV and superior magnetic characteristics of the GO, the HEV showed larger iron loss reduction ratio, torque increasement, and efficiency increasement compared with BEV.

This paper proposes a simple sensorless control method of a high-speed BLDC motor for cordless vacuum cleaner controlled using the 2-phase excitation method. In the high-speed region, the sampling number of pole-voltage is limited by the maximum switching frequency. Dual-side (high-side and low-side) PWM approach in the unipolar switching method is adopted to increase the sampling number in the non-excitation region. The detected pole-voltages are converted to the $alpha beta$-axis voltage of the stationary reference frame to remove the phase shift delay of phase pole-voltage and to get the continuous angle position. Rotor position can be estimated by the converted $alpha beta$-axis voltage, considering the sampling delay of the analog-to-digital conversion and the low-pass filter in the high-speed region. The proposed method is verified by experiments, and the results are compared to that of the conventional sensorless control. The proposed method shows an improved performance in the high-speed region because of the increased sampling numbers of the proposed dual-side PWM method.

HIL (Hardware in Loop) is an efficient and convenient tool for the test and verification of electrical drive system which requires high reliability and safety. With the application of high-frequency SiC inverter, the time scale is reduced below μs-level, as a result, the computation speed becomes an unignorable challenge for HIL system because of the strict real-time constraint. Under these circumstances, the development and applications of hardware with parallel process structure such as FPGA is a solution for computation acceleration on the hardware level. On the software level, unfortunately, most of the state-of-the-art numerical models and algorithms are based on sequential mechanism, as a result, the parallel algorithm is demanded to achieve further acceleration. This paper proposes a general method based on computation front to design parallel algorithm for real-time simulation. By analyzing numerical flow diagram, numerical integration method is optimized to realize acceleration derived from parallel segmentation. Simulation results show that good acceleration effect without great accuracy reduction is achieved.
硬件在环(Hardware in Loop, HIL)是对电气传动系统可靠性和安全性要求高的测试和验证的一种高效、便捷的工具。随着高频SiC逆变器的应用，时间尺度降至μs级以下，计算速度因其严格的实时性约束而成为HIL系统不可忽视的挑战。在这种情况下，FPGA等具有并行处理结构的硬件的开发和应用是在硬件层面实现计算加速的一种解决方案。然而，在软件层面上，大多数先进的数值模型和算法都是基于顺序机制的，因此需要并行算法来实现进一步的加速。本文提出了一种基于计算前端的实时仿真并行算法设计的通用方法。通过对数值流程的分析，优化了数值积分方法，实现了并行分割带来的加速度。仿真结果表明，该方法在不降低精度的前提下获得了良好的加速效果。

The electromagnetic vibration and torque ripple are crucial to the NVH performance of permanent magnet synchronous motor (PMSM). In this paper, take a motor with 9 slots and 6 poles as an example, the spatial and temporal orders of the force harmonics under the stator stationary reference frame and rotor rotating reference frame are derived. Both the theoretical analysis and the finite element method (FEM) demonstrate the differences between the force harmonic characteristics under the two reference frames. Then the radial and tangential vibrations on the stator and rotor are simulated and compared. The orders of force harmonics dominantly causing vibration and torque ripple are identified, respectively. The force harmonics, vibration and torque ripple are compared with motors before and after torque optimization as examples, and the intrinsic relation among them is revealed accordingly to give recommendations for optimization.

For interior permanent magnet synchronous motors (IPMSM), assembling permanent magnet with clearance fittings can make the procedure less challenging. While the position of the PMs may fluctuate as a result of centrifugal and electromagnetic forces, this may impair motor performance, particularly for high-speed PMSMs. In this paper, Maxwell stress tensor method and finite element method are used to analyze the force applied to PMs. A 1. 6kW,18krpm motor is employed to analyze the effect of PM location on motor performance. Finally, a prototype is made and tested to verify the correctness of analysis.

Distributed power systems using solar power, fuel cells, and batteries require a PCS (Power Conditioning System) that converts DC voltage into AC power. However, parasitic capacitance (CP) occurs between the distributed power input module and the ground due to the structural characteristics and installation structure of the distributed power system. In order to reduce the leakage current generated by the PCS for distributed power generation, and since the leakage current is affected by the common mode voltage, the size of the common mode voltage can be reduced and the leakage current blocked by using the insulation characteristics of the transformer. However, in the IT grounding method using a transformer, the leakage current, which is a zero component, cannot pass through the transformer, but a leakage current path is created due to the parasitic capacitance (CT) existing inside the transformer. In addition to the transformer, a new leakage current path occurs through the cable impedance depending on the cable length, and the leakage current increases after adding cable impedance compared to not adding it. Therefore, in this paper, the validity of the equivalent circuit was verified by analyzing the before and after adding of cable impedance in the IT grounding method through PCS modeling and comparing it with the experimental results.

The conventional HPMM-I and the proposed HPMM-II are designed and optimized based on the finite-element method (FEM). The effect of permanent magnet dimensions and offset angle on the proposed HPMM-I machine is investigated with emphasis on average output torque and torque ripple. The electromagnetic performances of two optimal machines are compared, and the proposed HPMM-II has significant advantages in torque characteristics and efficiency.
