Özet

In this study, an adaptive notch filter design is proposed to prevent flexible mode oscillations caused by the wings' structure in air-to-surface missiles. The proposed filter detects oscillations and prevents vibrations by simply changing the filter coefficients. The algorithm first identifies any existing oscillations and then calculates the corresponding oscillation frequency by satisfying the stability conditions of the filter such that poles of the notch filter are located within the unit circle in the z-plane. With the designed algorithm, the notch filter can be easily integrated into real-time applications because of the low resource consumption and simple structure of filter.
