Car Stable Platform For The Servo Control System Design

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 emphasizes the servo control design of commander's panoramic sight in integrated vehicle electronics system. Several key factors influencing the stabilization of the platform have been obtained through modeling analysis of components in the platform. Section 5 details how to correct the above factors which influencing the image stabilization. The possibility of the correction is validated through experiment. In the end, the design for servo control of the stabilized platform is completed.
