摘要
随着惯组/GPS组合导航技术的应用,针对航弹低成本和一体化制导系统的新要求,提供了一种以双DSP+FPGA为核心的低成本、高性能、高可靠性一体化制导与控制系统设计方案。采用高速实时信号处理技术和大规模可编程器件,合理分配功能并充分利用和共享FPGA资源,相对传统双计算机任务系统大大减小了体积、功耗和成本,同时又完全保留了传统设计中双机系统导航处理和飞行控制相对独立完成的优点。重点讨论了系统的任务划分、导航任务平台和飞控任务平台设计,并给出了双机通信的设计方法。经总体系统应用验证,系统运行稳定可靠,具有较强工程应用价值。
With the applications of IMU/GPS integrated navigation technology and new requirements of bomb guided system cost and Integrated Guided System,this article provides a kind of integrated control and guide system design.This design is a low cost,high performance,high reliability at the core of DSP＋FPGA.Rationally allocate the high speed and real time signal processing technology and the large scale programmable devices.Furthermore it make full use of these resources which also can be shared.Com-pared with the traditional double computer task system,it greatly reduces the size,power consumption and costs.While it fully retains the advantages of the traditional design which has the dual system navigation process and independent flight control.It focuses on the division of system tasks,navigation platform and flight control platform.In addition it provides the method of the double machine communication.This system is reliable after application of the overall system verification.It will have high engineering value.
