摘　　要：为了提高光电跟踪控制系统可靠性和实时性,设计了一种基于FPGA的控制系统。该控制系统以一块FPGA芯片为核心,主要完成传感器信号处理,控制算法实现,脉宽调制方波生成,与上位机通信等任务。采用Xilinx公司的ISE7.0平台进行开发,并用层次化和模块化的方式进行设计。实验结果表明这种设计方法使系统以比较低的成本获得了很高的处理速度,从而提高了系统的性能。In order to improve the reliability and real-time capability of the opto-electronic tracking system, a FPGA-based control system was designed. Tasks such as processing of sensor signal, implementation of control arithmetic, Pulse Width Modulation （PWM） wave generation and data communication with upper computer were performed in a single FPGA chip, which was core of the system. The platform for developing was Xilinx＇s ISE7. 0, and layered method and modularization were applied in the design. Experimental showed that the system could achieve very high processing speed with lower cost, and have better performance.
