AI Technical Summary
Existing servo systems suffer from problems such as inconvenient data acquisition, data loss, and complex on-site operation in mechanical resonance suppression. Furthermore, the FFT matrix calculation is time-consuming, making it difficult to meet the requirements of high-frequency real-time data interaction.
By employing FFT technology and a digital notch filter, a discrete Fourier transform is performed through an acquisition and sorting module. Combined with a radix-2 FFT algorithm and butterfly operation, the resonant frequency is quickly determined. An adaptive notch filter is then used to suppress resonance, reducing the computational load of the FFT matrix and enabling real-time monitoring and analysis.
It achieves low-cost and high-efficiency suppression of mechanical resonance, reduces damage to mechanical devices, improves the control accuracy and performance of servo systems, facilitates field applications, and simplifies operation procedures.
