摘要

提出了一种永磁同步电机的无传感器矢量控制算法。该方案使用DC-Link中的单个电流传感电阻与线性参数变化(LPV)观测器相结合来重建电机的相电流。将这些重构的相电流作为模型参考自适应系统的输入，以估计电机的角度和速度。因此，DC-Link电流传感器是整个系统中唯一可以用于电机控制的传感器。所提出的控制方案在32位微控制器上实现。给出了燃油泵电机实时控制的实验结果。

Sensorless vector control of PMSM with observer-based phase current reconstruction using only a DC-link current sensor

This paper presents a sensorless vector control algorithm for permanent magnet synchronous machines. This scheme uses a single current sensing resistor in the DC-Link in combination with a linear parameter varying (LPV) observer to reconstruct the phase currents of the motor. These reconstructed phase currents are used as input to a model reference adaptive system in order to estimate the angle and the speed of the motor. The DC-Link current sensor is consequently the only sensor in the whole system which can be used for motor control. The proposed control scheme is implemented on a 32-bit microcontroller. Experimental results of the real-time control of a fuel pump motor are presented.
