The naval gun servo system requires high dynamic tracking accuracy. In addition, the resonance point of the system changes at any time due to the influence of sea weather and wind waves. Therefore, the traditional off-line detection method of resonance point is not suitable for naval gun servo system. According to the characteristics of naval gun servo system, an on-line resonance suppression method based on notch filter is designed in this paper. The resonance frequency point is detected by fast Fourier transform, and then the notch filter is adjusted on-line parameters. The simulation results show that this method can suppress the resonance problem of naval gun servo system on line.
