摘要
针对伺服系统在等速运动中出现的末端谐振问题,该文章设计了一种滤波深度和滤波宽度可调的陷波滤波器。采用FFT频谱分析法,把时域信号转换为频域信号,通过频率提取算法获取谐振频率。最后通过试验验证了所述陷波滤波器的有效性。
Aiming at terminal resonance problem of servo system in constand speed motion,in this paper,a notch filter with adjustable filter depth and filter width was designed.FFT spectrum analysis method was adopted to convert time domain signals into frequency domain signals,and resonance frequency was obtained through frequency extraction algorithm.Finally,the effectiveness of the notch filter was verified by tests.
