摘　　要：为了稳定可靠地实现某天线转台伺服系统的圆扫、扇扫和定位3种工作方式,文中介绍了一种基于PC104的伺服系统的设计原理及软硬件实现方法,软件采用C语言编写。具体介绍了系统控制方式的设计及一种天线阵面风阻力矩、惯性力矩和摩擦力矩的计算方法,在此基础上讨论了驱动元件选型的计算。通过样机和多批次的实际使用验证,结果表明,该伺服系统设计合理、工作稳定、定位准确、安全可靠,满足所有技术要求。To implement a stable and reliable antenna turntable servo system which functions circular scan- ning, fan scanning and positioning. In this paper, the design principle and software/hardware implementation method of a PC104 based servo system are introduced, the software are written using C language. The design of the system control mode and the calculation method for antenna array wind drag torque, inertia moment and friction torque are introduced in detail. On the basis of these designs, the calculation of driving element selec- tion is discussed. Prototype and several actual operations show that the servo system is reasonably designed, is safe and reliable, can work stably, position accurately and meet all the technical requirements.
