Integrated Structures And Control Design Of Antenna Servo System

Radar servo system consists of mechanical construction and control system,they restrict and affect mutually.In the traditional electrical and mechanical servo system between structure and control system design is separated.The entire performance of the system always lead to the problems of massive structure?low tracking accuracy and long development cycle.In order to improve the performance of the entire system,it is necessary to design the structure and control system synthetically.Firstly,in this paper,modal method is used to establish the servo system analytical model,This model not only guarantees the accuracy of analysis,and can be directly used for the control object.Secondly,an integrated optimization model is set up using H_?control method.The optimum of tracking performance,robust performance and structure performance are realized through selecting structure parameters and controlling gain.At last,the modeling and Simulation of a radar antenna pedestal structure shows that the integrated design can obviously improve the system's stability and reduce the response time.It also shows the superiority of integrated optimization.
