Abstract

本发明公开了一种获取伺服***频率特性的方法、电子装置和存储装置，该方法包括：在至少一个指定频率范围内，对伺服***依次提供不同频率的正弦激励信号以对伺服***的输出信号进行分步扫描；在所述分步扫描的每一步中，对所述伺服***的输出信号进行同步整周期采样，获取不同频率点处所述伺服***的所述输出信号的幅值和相位；根据所述不同频率点处所述伺服***的所述输出信号的幅值和相位以及所述正弦激励信号计算得到所述伺服***的频率特性。通过对伺服***提供不同频率的正弦激励信号，并对伺服***的输出进行同步整周期采样，可以改善或消除频谱分析过程中的频率泄露和***非线性模态特征，从而提高计算精度。因此，本发明可以提高获取到的伺服***频率特性曲线的精度，有助于伺服***的精确控制。
