英文摘要	To address the problem of mechanical resonance in the control system of an aeronautical optoelectronic stabilization platform, a novel structural filter based on a double-T notch filter was proposed in this study. The new structure filter, consisting of two double-T notches and a low-pass filter, could suppress both resonant and anti-resonant peaks while overcoming the problem whereby a single notch filter could not deal with anti-resonance. Compared to that of the double quadratic filter, the parameter adjustment of the structural filter was more flexible, and its peak size and width can be simultaneously adjusted. In addition, the experimental results show that the resonance curve fitted by the structural filter matches the actual sweep curve better. The stability accuracy of the control system is improved by 5.74 times and the closed-loop bandwidth is increased by 4.54 times after the structural filter is added to compensate the model. The new structure filter clearly aids in suppressing mechanical resonance and improving the performance of the control system. 2019, Science Press. All right reserved.
