摘要
高性能雷达伺服控制器是雷达设计中的一个重要问题。在这篇文章中,采用ARM+FPGA结构设计了一种高性能的雷达伺服控制器,设计了ARM的最小系统,在这基础上添加了必要的外围设备,包括UART、USB和以太网通信等构成能在上位机的控制下工作的嵌入式系统,简化硬件和软件设计,充分利用FPGA的硬件连接方式和ARM强大的运算和管理能力,使ARM和FPGA二者的优点相结合,兼顾速度和灵活性。实现模糊神经网络PID控制算法。实验仿真表明:该控制算法对系统具有良好的控制效果,在系统的动静态性能和鲁棒性均优于常规PID控制。
High-performance servo controller of radar is always an important target to study. In this article, using ARM＆FPGA structure as High-performance servo controller of radar, ARM＇s the smallest systems has being designed, on this basis that add the necessary peripheral equipment,including UART, USB and Ethernet communications can pose a PC under the control of the embedded system, simplifying the hardware and software design, make full use of the FPGA hardware connections and ARM powerful computing and management capabilities, and make full use of the ARM＆FPGA on-chip resources and capacity can be expanded,and with FNN PID control,a control algorithm has been achieved. The result of experiment proves：the algorithm of the system has good control and is more advanced than normal PID in analyzing the performance of system＇s activity and robustness.
