【摘要】 飞／推综合控制优化计算机实时接收飞机和发动机的信息，利用内嵌的优化模块，对发动机控制指令进行修正以优化推进系统性能，使飞机和发动机的整体性能达到最优。本文提出基于DSP和CAN总线的飞／推综合控制优化计算机设计方案，并研制成功原理样机。 首先研究了优化计算机原理样机的硬件电路设计方案，阐述了硬件电路的设计特点。然后概述了发动机实时优化的原理及优化控制算法的计算步骤，并开发了基于前后台模式的优化控制逻辑软件。为了提高优化控制的实时性和可靠性，研究了基于嵌入式实时操作系统(μC／OS-Ⅱ)的优化计算机多任务设计。构建了实物在回路的飞／推综合控制仿真试验系统，进行了最大推力模式和最小油耗模式的优化仿真试验。试验结果表明两种优化模式下，飞／推综合控制的优化算法可以显著提高发动机性能，也验证了该优化计算机设计方案是可行的。更多还原

【Abstract】 A design method of integrated flight/propulsion control(IFPC) optimization computer based on Digital Signal Processor (DSP) and Control Area Network (CAN) bus is presented . Optimization computer trims the engine control inputs based on the input information from the aircraft and engine, which offers significant performance improvements of the propulsion. Hardware architecture and software realization of the optimization computer are discussed and implemented. RTOS μC / OS - II is ported to optimization computer to improve real-time controlling and enhance stability .Hardware-in-Loop simulating system of IFPC is built to research the Digital simulations, which are conducted with two optimization modes: maximum thrust mode and minimum fuel consumption mode. Simulation results presented here demonstrate that during accelerating flight at constant altitude thrust increases up to approximately 12 percent in the maximum thrust mode, and at subsonic cruise specific fuel consumption decreases up to 2 percent in the minimum fuel consumption mode. This optimization computer has implication for improving performance of military aircraft.更多还原
