Research On Multi-trajectory Marching And Pointing Tracking Control Of Missile-borned Reconnaissance System

In this paper,a new integrated system for striking,reconnaissance and communication is designed based on a long-range ballistic missile,and the trajectory characteristics of the system and the control system of observation(reconnaissance)and relay(communication)platform are studied.First of all,the development of target damage assessment and the current research status of reconnaissance system are introduced in this paper.Meanwhile,the research status of pointing tracking control is introduced,especially some basic control methods commonly used in engineering at present.Then,the general structure of reconnaissance system is analyzed and the design drawing is shown in this paper.Then,according to the research content of this paper,the structure of observation platform and relay platform are mainly introduced,the characteristics of the two platform are also analyzed.The analysis of the position control block control system are the same in two platforms and is given.Secondly,according to the characteristics of the observation platform and the relay platform,the trajectory of observation platform and F-type relay platform are designed.In the process of ballistic design,the main constraints are the space size constraint,the missile environment constraint and the ballistic constraint,which are not reserved for a certain type of missile.For observation platform and relay platform,the factors that affect the matching between ballistics mainly include separation time,separation angle and separation time.Based on these three elements,a corresponding evaluation model is established,and finally the trajectory of two platforms is determined.In the fourth chapter,a similar analysis method is used to analyze the N-type trajectory of observation platform and relay platform.Finally,the simulation result and the ballistic parameter table are given.Finally,in order to realize the designed optimization trajectory,the overall scheme of guidance control system is proposed subsequently.On the basis of this,aiming at the characteristics of the observation platform and mid-level flight platform,the modern control theory is used to design the adaptive sliding,the controller design is given and the stability of the system is derived.Finally,the simulation is carried out according to the designed control law.The simulation results show that the designed control system can make the observing platform have a good tracking performance.
