The Research And Design Of Accurate Servo Control System To Cawierbased Stabilized-platform

With the wide application of electro-optic reconnaissance, surveillance and tracking to military, the requirement for system is increasing, and also the requirement for image stabilization is strict. The nature for image non-stabilization is the relative motion between axis of the system and the target including translation and angular motion, in which relative angular motion has great effect on image. There are two cases that result to angular motion between the axis of sighting system and target: one is the motion of the target; the other is the motion of the vehicle. Normally, as the stabilized system only considers the angular motion of the isolated vehicle, the design of stabilized system mainly uses the servo control method combining optics and electronics.This paper focuses on a photoelectric tracker in improving the electro-optical tracking servo system stable platform on the accuracy and stability. By analysing the composition of the photoelectric instrument various parts, found out several important factors that affected the stable platform's stable accuracy ,and analysed those factors one by one, concluded that how to improve the stable accuracy of the stable platform servo control system.
