摘要

内部永磁同步电机(ipmms)用于各种应用，需要高效率的控制。最大转矩/安培(MTPA)控制是一种高效控制永磁同步电动机的方法。然而，由于电机参数随磁饱和而变化，MTPA控制不容易实现。在此，我们提出了一种完全在线、自动的MTPA控制方法。为了在驱动电机时找到MTPA点，需要对整个磁链曲面进行预测。因此，在考虑磁交叉饱和影响的特定电流条件下，磁链曲面由传感器信息近似成一个平面。利用估计磁链平面和梯度上升法实现MTPA控制。仿真结果表明，该算法在两个搜索周期内获得最大转矩，搜索周期为0.06 s。该方法适用于较宽的电流范围。

Maximum Torque per Ampere Control of IPMSM Using Online Flux Linkage Plane Estimation Considering Cross Saturation

Interior permanent magnet synchronous motors (IPMSMs) are used for various applications and high efficiency control is required. Maximum torque per ampere (MTPA) control is a method to control IPMSMs with high efficiency. However, since the motor parameters vary with magnetic saturation, MTPA control cannot be easily realized. Here in, we propose a fully online and automatic MTPA control method. To find the MTPA point while driving the motor, it is necessary to predict the entire flux linkage surface. Therefore, the flux linkage surface is approximated by a plane from the sensor information at a specific current condition that considers the effect of magnetic cross-saturation. MTPA control is achieved using the estimated flux linkage plane and the gradient ascent method. The simulation results reveal that the torque maximized in two search periods, which was completed in 0.06 s. The proposed method is effective for a wide current range.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
