摘要：
Based on the analysis of relationship among the power, torque and stator flux-linkage, the efficiency optimization of the interior permanent magnet synchronous motor drive system for urban rail traction based on instantaneous power control is presented during the transiently operating process of accelerating and braking region. The goal of the method is to control reactive power as zero and improve power factor at the same output of active power. Instantaneously input active and reactive power are changed by the control of stator flux amplitude and position angle to improve the system efficiency, torque output capability, and response speed. Efficiency optimization control system is implemented using a STM32F103 embedded microcontroller. The validity of the proposed strategy is proved by the simulation and experimental results.
摘要：
The interior permanent magnet synchronous motor (IPMSM) can make use of the magnetoresistive effect to improve its efficiency and speed characteristics, so that it is suited to railway vehicle. To solve electromagnetic torque output insufficient of IPMSM using the traditional field weakening control method, the field weakening control strategy of interior permanent magnet synchronous motor for railway vehicle was studied in the paper. A novel method of modifying the current reference and field weakening based on the maximum electromagnetic torque at full speed (whether in the base rate areas or in the field weakening region) were proposed. The method consists of two parts, one is the determination of the field weakening region, and another is the current reference modification. The field weakening region was determined. The reference current vector and the maximum electromagnetic torque expression were obtained by solving the voltage limit equations and the current limit equations in the field weakening region I; the reference current vector was obtained by solving the voltage limit equations and the electromagnetic torque equations in the field weakening region II. The current reference was modified by the field weakening direction and the magnitude of the voltage error according to the field weakening region. The simulink model was founded by Matlab and the experiment platform of the 100 kW IPMSM field weakening control system was implemented using a TMS320LF2407A DSP. The validity of the proposed strategy was proved by the simulation and experimental results.

摘要：
To improve the steady state efficiency of interior permanent magnet synchronous motor system(IPMSM), the intelligent integrated online optimal control strategy of IPMSM efficiency optimization was presented. The intelligent integrated control technology and torque compensation method were combined to the system. The method of adaptive fuzzy logic to adjust direct-axis current was adopted in the first half search, using the adaptive step size to reduce the torque fluctuations. The golden section search method was adopted in the next half search to speed up the search process and improve its convergence. While in the whole process, the torque correction program was introduced to compensate the torque current in real-time and resolve the torque pulsation problem in the regulation process of the excitation current. The dynamic and static performances of the system are improved. A 100kW IPMSM efficiency optimization intelligent integrated control system was implemented using a TMS320LF2407A DSP. Experimental results prove the validity of the proposed strategy.

摘要：
The chaotic phenomena of a permanent magnet synchronous motor (PMSM) under certain circumstances were studied based on the error analysis of the stator flux observer output by parameter change of the permanent magnet synchronous motor, PMSM model with chaotic features was built, and the chaotic curves were gained based on PMSM mathematic model. A dual fuzzy controller was designed for the direct torque control (DTC) system of the PMSM. The simulation results prove that control effect on the chaotic phenomenon of the PMSM-DTC system by the dual fuzzy control is good, and the dynamic and static performances of the PMSM-DTC system will be improved. Also the ripple of torque and flux can be reduced and the response speed can be improved.

摘要：
Based on analysing the factors that cause torque ripple and analysing the nonzero demagnetism/in magnetism component in stator current for the typical direct torque control system of the permanent magnet synchronous motor, this paper presents a novel control system which directly controls the magnetizing component of the stator current with two-level bang-bang controller.The improvement eliminated the component which in the stator current did not hope, enhanced the exchange transmission system efficiency. It is simple and easy to implement. The simulation results indicate static and dynamic performance of the new system is improved and torque ripple is decreased, simultaneously still retains the better control performance and higher efficiency than the typical direct torque control system.
