对表面贴装永磁同步电机驱动器无传感器控制的需求迅速增长。在开发的各种无传感器控制技术中，松井目前基于模型的方法和扩展卡尔曼滤波器方法引起了广泛关注。然而，这些控制方法的性能在强烈干扰或传感故障下可能会严重恶化，甚至可能变得不稳定。本文对用于表面安装永磁同步电机驱动器的扩展卡尔曼滤波器、弹性扩展卡尔曼滤波器和基于无味卡尔曼滤波器的无传感器直接扭矩和磁通控制方法进行了比较研究。计算机仿真研究和硬件实现结果表明，在无传感器直接扭矩控制应用中，弹性扩展卡尔曼滤波器和无味卡尔曼滤波器比传统扩展卡尔曼滤波器具有更高的效率和优越性能。
The demand for sensorless control of surface-mounted permanent magnet synchronous motor drives has grown rapidly. Among various sensorless control techniques developed, Matsui’s current model-based approach and the extended Kalman filter approach have gained much attention. However, the performance of these control methods can be severely worsened or may even become unstable under strong disturbances or sensing failures. This paper presents a comparative study of the extended Kalman filter, the resilient extended Kalman filter, and the unscented Kalman filter-based sensorless direct torque and flux control approaches for the surface-mounted permanent magnet synchronous motor drives. Computer simulation studies and hardware implementation results have shown the efficiency and superior performance of the resilient extended Kalman filter and the unscented Kalman filter over the traditional extended Kalman filter for sensorless direct torque control applications.
