The Design Of Guidance And Control System For Cruise Missile

With the rapid development of modern military technology,the future information war has put forward higher requirements on the precision and maneuverability of the tactical missile.The traditional STT control method can not meet the design requirements.In this case,the BTT control method has been paid attention and developed rapidly because of its advantages such as high aerodynamic efficiency,long range and so on.Based on the background of the cruise missile,dispenser,this paper explored learning and engineering guidance and control system for BTT missile.Firstly,the thesis summarizes the BTT Missile’s domestic and foreign development situation and characteristics,for comparative analysis of BTT missile with the STT missile,next summarizes the application status of BTT control technique and the facing problems,and the development prospect of BTT were analyzed.Three kinds of coordination turning methods used in the design of BTT driver are discussed,and their advantages and disadvantages are analyzed.In this paper,the structural characteristics of the two circuit and three circuit overload driver are introduced in detail,and the design method is proposed.Design of two loop and three loop pitch and yaw overload autopilot,designed two loop roll autopilot.Simulation and analysis of the impact of the three channel fast on the system.Finally,the introduction of all the coupling items,compared with the introduction of coupling before and after the driver’s response curve and analysis of the impact of each coupling on the autopilot.The concept of singularity is proposed.The basic reason of singularity is analyzed by mathematical method.Two solving strategies are proposed for the phenomenon of the rolling angle jump in small signal: the linear interpolation smoothing algorithm and the BTT/STT hybrid control.On the basis of the analysis of the two strategies,the simulation analysis is conducted to verify the effectiveness of the method.
