The gate position during lifting and lowering is a plant. The system should provide the movement with a minimum alignment error. The paper contains a brief description of the equipment, the structure of the control system, the experimental data. The spectral analysis of signals present in the system is performed. Designed band-stop filter reduces the impact of noise on the formation of the control signal. A numerical study of the filter concludes its applicability.lock gatesshipping lockautomatic control systemspectral analysisband-stop filterButterworth filterподъёмно-опускные воротасудоходный шлюзсистема автоматического управленияспектральный анализполосно-заграждающий фильтрфильтр Баттерворта[Электрогидравлические следящие системы/ Под ред.
