针对家用电器用永磁同步电机，提出了一种简化的矢量控制方法。通过去掉传统矢量控制器中的速度调节器和电流调节器，简化了控制结构。输出电压基准通过使用电机参数、转速命令和电流基准进行类似前馈的计算来确定。在静态特性方面，由于电压参考是在矢量空间中计算的，所以该矢量控制方法与传统的矢量控制方法几乎是等同的。提出了一种实用的转子位置估计方程，并将锁相环控制方法应用于无位置和速度传感器的永磁同步电机驱动。给出了两种控制增益的设计方法。最后，通过仿真和实验验证了该控制方法的有效性。
A simplified vector control is proposed as a driving method of permanent magnet synchronous motor (PMSM) for electrical household appliances. Control structure is simplified by eliminating the speed regulator and the current regulator from the conventional vector controller. Output voltage references are determined by feedforward-like calculation using motor parameters, rotation speed command, and current references. In the static characteristic, the proposed vector control method is almost equal to the conventional one, because the voltage references are calculated in the vector space. A practical estimate equation of rotor position is proposed, and the phase locked loop control approach is em-ployed to drive PMSM without position and speed sensors. Design method of two control gains is given. Finally, the e ff ectiveness of the proposed control is verified by simulation and experiments.
