Research On Seeker Control Technology Based On Roll Up Structure

With the rapid development of science and technology,the world military science and technology has also had earth-changing development,air-to-air missile as a more important part of the weapon system has also been the attention and research of many military experts at home and abroad.This paper is based on the background of air-to-air missile in weapons and equipment system,and combined with the research of the current specific scientific research topic,the technical research on the control direction of roll-elevation seeker is carried out.Based on the application background of air-to-air missile weapon system and the development requirements of specific pre-research projects,this paper studies the technical problems related to the control direction of the rolling heeling seeker,which provides a theoretical basis for the research on the control count of the rolling heeling seeker and its application in the air-to-air missile in China.Firstly,the development trend of air-to-air missile is reviewed,and the demand of air-to-air missile to adapt to modern war and the development situation of air-to-air missile in close range combat at home and abroad are analyzed in detail.The development theory of seeker technology is investigated in detail.On this basis,combined with the tracking principle of the current roll-upward seeker,the research object of this paper is determined--the seeker based on roll-upward structure.Secondly,the overall design of the servo control system of the rolling-upward seeker is introduced.Through the function and composition of the seeker and seeker related to the main part of the technical indicators.Then the seeker is classified and introduced according to different angles,and the hardware structure of the servo control system of rolling and lifting seeker is selected.According to its hardware structure,the composition of its servo control system is briefly described.At last,two key technical problems in the design of the control system of the roll-upward seeker are presented.Thirdly,the key technical problems in the design of the control system of the roll-upward seeker are analyzed in detail.Firstly,the working principle of the seeker servo control system is described,and the design requirements of the seeker stabilization servo platform are put forward.According to the requirements,the servo control system is designed,and the closed-loop control algorithm is simulated and the key components are selected.Secondly,the extraction technology of the line of sight angular velocity of the seeker and the process of solving the line of sight angular velocity guidance signal by converting the line of sight coordinate system to the projectile coordinate system of the rolling-inverting seeker are described in detail.Finally,put forward the control of the roll-pitch type seeker system platform for software and hardware design,control system is described in detail based on STM32103VET6 platform design,and implementation in this argument the roll-pitch type seeker based software structure of control system,completed the system has carried on the modular design,and the integration of various modules alignment,in order to meet the roll-pitch of the seeker the use requirements of the control system.
