摘    要:为了克服舰船摇摆及风阻力矩干扰所造成舰载光学测量设备跟踪稳定性下降、目标丢失的影响,伺服系统通过接收主控微机提供的船摇信息,将船摇速度校正放大后引入速度回路,实现经纬仪的自稳定跟踪;通过对PXI总线技术进行探讨,分析PXI总线的规范和特点,结合伺服控制器的工作原理和组成,基于PXI总线的FPGA、DSP应用以及外围接口电路设计,大大减小了系统的体积,提高系统集成度、可靠性和稳定性。

关 键 词:舰载光电经纬仪  伺服控制  PXI总线  DSP

Abstract:In order to overcome the influence with track stability decline and target lost of the carrier-borne photoelectric theodolites because of the waving and wind resistance moment of the naval vessel, the servo system introduce the vibration velocity to the speed loop after being processed through accepting the vibration message from the computer. The theodolite auto steady track is realized. Through the discussion about PXI bus technology, analyzes its criterions and characteristics, according to the principles and constitutions of servo controller,based on FPGA and DSP and the peripheral interface circuit design with the PXI bus, the system volume is reduced greatly. The integration and reliability and stability of the system is improved.
Keywords:DSP  carrier-borne photoelectric theodolites  servo-control  PXI bus  DSP
