Study On Computer Control For Gyro Stabilized Sighting System Of Airborne Optoelectronic Pod

Gyro Stabilized platform of dural axes is an important field among the applications of the inertial technology. And because of its broad application in recent years, stabilized sighting system of airborne optoelectronic pod has become a hotspot nearly in those countrys with powerful science and technology. Stabilized sighting system of airborne optoelectronic pod is one kind of airborne equipment, which can quickly capture and lock, automatically track both flying objects in the air and moving objects on the ground.Considering the advantage of computer control, digital technique has been more and more applied in the study of stabilized sighting system of airborne optoelectronic pod. For the specifically structure and characteristic of stabilized sighting system of airborne optoelectronic pod, this paper presents a design with DSP divice of TMS320F2812 by TI. Conside that the system parameter will be change in the bad operating environment, deferent control algolrithm has been taken into account, which having realized the design of stabilized sighting system of airborne optoelectronic pod. Author designed a set of controller based on DSP applied for stabilized sighting system of airborne optoelectronic pod from arithmetic hardware to software.This paper firstly introduces the background, research significance, principle and overall plan of the Stabilized sighting system of airborne optoelectronic pod, and nextly introduces the analysis, simulater and design for structure of stabilized sighting system. And then, a detailed computer control software design and hardware platform based on the design of TMS320F2812's little system and another driver circuit for stabilized sighting system was given. Stabilized sighting system of airborne optoelectronic pod achieves good results with exception in the field of speed, accuracy and anti-interference ability.
