Design and Achievement of the Antenna Servo System Based on 80C196MC

介绍了一种天线伺服系统的设计与实现方法。分析比较了各种交流伺服系统,对系统驱动方案进行了研究与设计,提出了永磁同步电机作为驱动机构的伺服电机。为了确保驱动系统的高精度和高稳定度运行,系统采用绝对位置光电编码器作为位置反馈,并设计了位置、速度、电流三环控制,控制软件采用面向对象的程序设计方法,将消息驱动机制应用于软件的设计和开发之中,完成了以80C196MC为核心的控制系统硬件设计和软件设计与调试。系统进行了一系列严格的实验,大量实验数据表明,该系统方案合理、可行。

A new kind of design and achievement of the antenna servo system based on 80C196MC is developed.On the basis of particular introduction of several AC servocontrol technologies,the permanent magnet synchronous machine is adopted as the driver motor.To reach the achievement of a high and steady precision of the system,an absolute position photoelectric encoder is used as the feedback device,and the closed loop control mode including position feedback,velocity feedback and current feedback is designed for the driver motor.The object-oriented method is used for the system analysis and study.The hardware and software of the system have been designed and debugged on the CPU of special motor controller 80C196MC.Then the experiments are done,which show that the system is steady-going and reliable,and the scheme is reasonable and feasible.
