Develop And Design Of The Servo Simulation System For Seeker

Seeker servo control section is an important part of the seeker,its main function is to control the antenna to scan the target,intercept and track it,then to guide the missile hit the target accurately.Therefore,the seeker servo control performance affects the quality of member seeker missile guidance functions directly.In order to do some simple experiment for seeker servo control section,this paper combines the mechanical load and high-speed performance of analog data acquisition card and data communication card,and it uses LabVIEW graphical programming capabilities to develop a seeker servo simulation system.The main research work of this treatise are as follows:Firstly,the frame design of the seeker follower simulation system is completed,then introducing the composition and working principle of seeker servo simulation system and its main work status,and it also analyzed the seeker servo control means external interface signal,on the basis of them,it completed the hardware frame design.Then we selected the different types of hardware and described the features of several types virtual instrument,according to the actual situation to choose the basic implementation of this topic.Secondly,The specific design and simulation analysis of load modules is completed.According to the needs of the subject,we designed a mechanical dummy load,in order to verify this design,we used Pro / e to establish a visual model and do some simulation analysis though ADAMS.According to balance equations to complete model of the control system.To real-time control the control system based on the Stable Boundary tuning PID control parameters,and the use of ADAMS and MATLAB to simulate load joint simulation analysis,the results showed that the flywheel in a relatively stably from the initial position close to the desired angle within a short response time,dynamics and control model established can accurately describe the actual work process,to provide a reliable basis for the development of physical prototypes.Then The software specific design of the seeker follower simulation is the completed system.According to the needs of the subject,designing the overall software modules and completing the flow diagram of the entire system.With the simple feature of the LabVIEW,the each module of the system specifically is designes.System is mainly achieved through ARINC429 bus protocol to make the seeker servo control section to complete the appropriate action depending on the control instruction PC software,mainly to meet the seeker servo system in the target scanning operation,a large field scanning working conditions,interception and tracking status,and a variety of other functions smoothly switching It also completed other functions,such as user login,data communication,data collection and analysis,and data management capabilities.Finally,it completed tests and analysis of the seeker servo system.According to the target scanning operation,a large field scanning operation,interception and tracking state to complete seeker servo control section of the overall test.It also gives some experimental data and the results of analysis.It provides sufficient experimental data and theoretical basis for the design of further experiments and systems.
