飞机燃油系统流量模拟控制系统研究

Research on Flow Simulation Subsystem of Aircraft Fuel System

阐述了飞机燃油系统流量模拟控制系统的重要性并分析了传统控制方案的缺陷。对传统流量控制系统结构作出适当改进,以解决分段测量所引起的切换过程数据不精确问题。采用单神经元PID控制器,在保证大范围动态跟踪效果稳定的前提下,很好地抑制了切换过程中的抖动,具有较好的控制效果。

The significance of the flow control subsystem of ground simulation test for the aircraft fuel system is presented and the deficiency of the traditional control scheme is analyzed.An improvement scheme is designed to resolve the data inaccuracy caused by the subsection measuring.The single-neuro PID controller is used to stabilize the curve tracking of wide-range and to restrain the fluctuation in the flow switchover process.The results of the simulation show that the algorithm has a preferable control effect.
