The article presents a general framework valid for the high-frequency excitation-based position observer for low-speed sensorless control of synchronous reluctance machines. A finite-control-set model-predictive-control technique is proposed accordingly, exploiting the switching current ripple for the position estimation. The position error due to cross saturation is inherently accounted for. The proposed scheme is integrated with an adaptive projection vector for position error estimation for high speeds region through a simple fusion structure for a smooth transition. The performance of the proposed technique is validated on a 1.1-kW synchronous reluctance motor test bench.

无传感器同步磁阻电机驱动：在投影矢量框架中使用有限控制集 MPC 的全速方案

本文提出了一个适用于同步磁阻电机低速无传感器控制的基于高频激励的位置观测器的通用框架。相应地提出了一种有限控制集模型预测控制技术，利用开关电流纹波进行位置估计。由于交叉饱和引起的位置误差是固有的。所提出的方案通过简单的融合结构与用于高速区域位置误差估计的自适应投影矢量相结合，以实现平滑过渡。所提出技术的性能在 1.1 千瓦同步磁阻电机测试台上得到验证。
