摘　　要：随着移动卫星通信技术和汽车导航系统的迅速发展,车载智能天线系统得到了越来越多的应用,因此如何设计一个性能良好的车载智能天线跟踪系统是一个重要的问题;文章介绍了一种利用微控制器LPC2129对车载天线跟踪系统进行控制的方法,使得车载天线跟踪系统这种具有非线性、工作时所受干扰大以及控制精度和实时性要求都比较高的系统得到良好的改进;试验表明,该系统采用跟踪算法能取得良好的跟踪效果。With the fast development of satellite mobile communication and vehicle navigation systems, the vehicle smart antenna tracking system has become widely applied. So how to design a good smart antenna tracking system has become an important issue. Thus a control method is proposed, which uses microcontrollers LPC 2129 to control vehicle smart antenna tracking system and make this system, which is non-linear, strongly disturbed and requires good control precision, high real-time performance, well improved. Experiment shows that this system could achieve good result by using the tracking algorithm.
