Abstract

Abstract

To avoid obscuring the field of view, a photoelectric platform is usually placed on top of a lifting mast. The structural stiffness of the mast directly affects the stiffness of the photoelectric platform servo system and its dynamic performance. In actual use, it is deduced that an insufficient stiffness of the mast causes the photoelectric platform to resonate easily in the process of azimuthal rotation, causing it to work unstably. To solve this problem, a Butterworth low-pass filter, notch filter, and linear auto disturbance rejection control mode are introduced successively to suppress the resonance phenomenon of the lifting photoelectric pan tilt table. By comparing the advantages and disadvantages of the three methods, it is concluded that the linear ADRC method has the advantages of fast response, good resonance suppression effect, and good robustness, and is suitable for the control system of the lifting photoelectric photoelectric platform.
