【摘要】：混合励磁同步电机(hybrid excitation synchronous motor,HESM)具有调磁方便、调速范围宽等优势,在工业、军事领域应用前景广阔。该文在矢量控制和速度分区控制的基础上,针对HESM提出了一种铜耗最小化弱磁调速控制方法。该方法以电机铜耗最小化为目标,自适应地调节弱磁基速系数,在满足电枢端电压限制的条件下,对q轴电流、d轴电流与励磁电流进行最优配置。在深入分析弱磁基速系数对电机运行性能的影响的基础上,应用自适应控制方法对其进行调节以提高电机的调速范围、效率及动态特性等综合性能。最后,通过仿真和电机驱动实验验证了所提出的控制方法的正确性和有效性。结果表明,所提出的HESM弱磁控制方法,可实现电机综合性能的最优化控制。
[Abstract]:Hybrid excitation synchronous motor HESM has many advantages, such as easy to adjust magnetic field and wide speed range, so it has a wide application prospect in industrial and military fields. On the basis of vector control and speed zoning control, this paper presents a method of copper loss minimized weak magnetic speed control for HESM. This method aims at minimizing the copper loss of the motor adaptively adjusts the base velocity coefficient of weak magnetic field and optimizes the Q-axis current d axis current and excitation current under the condition of satisfying the limit of armature terminal voltage. On the basis of deeply analyzing the influence of base velocity coefficient of weak magnetic field on the performance of motor, the adaptive control method is applied to adjust the motor to improve its comprehensive performance, such as speed range, efficiency and dynamic characteristics. Finally, the correctness and effectiveness of the proposed control method are verified by simulation and motor driving experiments. The results show that the proposed HESM weak magnetic control method can realize the optimal control of the comprehensive performance of the motor.
