【摘要】：实现对永磁同步电机调速系统高性能控制的基础是准确的数学模型和电机参数,其中电感参数对电机的稳态和动态运行性能影响较大,而对于内置式永磁同步电机而言电感除了受凸极结构影响之外,还受磁路饱和等因素的影响。考虑到定子电流引起的磁路饱和效应与交叉耦合效应对电感的影响,基于矢量控制技术分别提出了d轴和q轴电感旋转辨识新算法,即d轴复合电流激励法和转矩调整法。为了提高电感辨识准确度,还采用基于电压误差曲线的补偿算法对逆变器非线性因素引起的输出电压误差进行了补偿。最后在电机控制实验平台上通过实验验证了提出的电感辨识算法的可行性和有效性。
[Abstract]:The high performance control of PMSM speed regulation system is based on accurate mathematical model and motor parameters. The inductance parameters have a great influence on the steady and dynamic performance of the motor. For the built-in PMSM, the inductance is affected not only by the salient pole structure, but also by the saturation of magnetic circuit. Considering the effect of magnetic saturation effect and cross-coupling effect caused by stator current on inductance, a new identification algorithm of D-axis and q-axis inductor rotation is proposed based on vector control technology, that is, d-axis compound current excitation method and torque adjusting method. In order to improve the accuracy of inductor identification, a compensation algorithm based on voltage error curve is used to compensate the output voltage error caused by nonlinear factors of inverter. Finally, the feasibility and effectiveness of the proposed inductance identification algorithm are verified on the motor control experimental platform.
