本文提出了一种用于无位置传感器的永磁电机驱动系统的新型 V/f 控制方法。与无传感器矢量控制不同，V/f 方法不需要高性能数字处理。本文提出了 V/f 控制的三个新颖主题。首先，展示了传统V/f控制的不稳定性，并提出了一种由高通滤波器和d轴电流反馈组成的稳定方法。之后，引入了一种高效率的控制策略。结果表明，无需显式估计 dq 轴即可实现条件 id=0，对应于 SPM 的高效运行。此外，由于该方法基于无功功率的评估、R_??_和e的知识。米。 f.不是必需的。最后提出了一种不需要磁通饱和来解码永磁体NS极的启动方法。由此产生的控制系统的结构非常简单，其有效性已通过使用1.5kW、3600r/min和3.7kW、7200r/min永磁电机进行实验证实。
This paper proposes a novel V/f control method for PM motor drive system without position sensor. Unlike sensorless vector control, V/f method does not require high performance digital processing.This paper presents three novel topics for V/f control. At First, instability of conventional V/f control is shown, and a stabilization method consisting of a high-pass -filter and a feed back from d-axis current is proposed. After that, a control strategy yielding high efficiency is introduced. It is shown that the condition id=0, corresponding to high efficiency operation for SPM, can be achieved without explicit estimation of dq-axis. Furthermore, since this method is based on the evaluation of the reactive power, knowledge of R_??_ and e. m. f. is not required. At last, a starting method that does not need flux saturation to decode NS pole of permanent magnet, is proposed. The structure of the resulting control system is very simple and its effectiveness has been confirmed experimentally by using 1.5kW, 3600r/min and 3.7kW, 7200r/min PM motors.
