Abstract
(EN) A method and device for measuring the distortion of a motor system, and a computer readable storage medium, the measuring method comprising: generating a logarithmic sweep signal and an inverse signal corresponding to the logarithmic sweep signal (S100); calculating an acceleration signal of a motor according to the logarithmic sweep signal (S200); solving a kernel function of a motor system according to the acceleration signal and the inverse signal of the logarithmic sweep signal (S300); and calculating the distortion of the motor system according to the kernel function (S400). By means of the described embodiment, the distortion testing time for a motor system can be shortened on the premise that the testing precision and the existing method are approximately the same, thus facilitating rapid production line testing.
(FR) La présente invention concerne un procédé et un dispositif de mesure de la distorsion d'un système moteur et un support de stockage lisible par ordinateur, le procédé de mesure comprenant les étapes consistant à : générer un signal de balayage logarithmique et un signal inverse correspondant au signal de balayage logarithmique (S100); calculer un signal d'accélération d'un moteur en fonction du signal de balayage logarithmique (S200); résoudre une fonction noyau d'un système moteur en fonction du signal d'accélération et du signal inverse du signal de balayage logarithmique (S300); et calculer la distorsion du système moteur en fonction de la fonction noyau (S400). Grâce au mode de réalisation décrit, le temps de test de distorsion pour un système moteur peut être raccourci en supposant que la précision du test et le procédé existant sont approximativement identiques, ce qui facilite le test rapide d'une ligne de production.
(ZH) 一种马达系统失真的测量方法及设备、计算机可读存储介质,该测量方法包括:生成对数扫频信号及和对数扫频信号对应的逆信号(S100);根据对数扫频信号计算得到马达的加速度信号(S200);根据加速度信号及对数扫频信号的逆信号求解马达系统的核函数(S300);根据核函数计算马达系统的失真(S400)。通过上述实施方式,能够在测试精度和现有方法近似相同的前提下,缩短马达系统的失真测试时间,便于进行快速产线测试。
