摘要
飞行控制计算机 (FCC)作为飞行控制系统的核心 ,担负着多种任务。随着系统功能的日益增多 ,飞行包线的不断扩大 ,模拟式FCC已经越来越不能满足系统要求。针对目前FCC向数字式、智能化方向发展 ,本文利用高速DSP芯片 ,结合复杂可编程器件 (CPLD) ,设计出一种集高可靠性、高集成度、高精度于一体的新型FCC ,最后在此基础上外加了数据采集卡组成闭环半物理系统 ,并进行了仿真。仿真结果表明 ,本文这一全新尝试完全可行 。
Flight control computer (FCC), as the core of a flight control system (FCS), takes on multiple tasks for the FCS, with the increase of function and the expansion of mission envelope, analog FCC can't meet requirements of FCS. In view of a FFC tendency towards digitization and intellectualization, a high reliability, high integration and high precision digital FCC is designed using a DSP(as processor) and CPLD. The FCC combined with a data collection board forms loop semi physical system, system simulations are performed, The simulation results show that this design is practicable and has a wide application prospect.
