Research and application of steady flow intake control method in icing wind tunnel engine intake simulation system

  • 摘要:

    针对结冰风洞发动机进气部件试验稳流量进气控制难题,结合提供进气条件的发动机进气模拟系统的工作原理,提出采用卡尔曼滤波无模型自适应控制方法,通过建立系统动态线性化数据模型,利用卡尔曼滤波对实际动态流量输出做真值预估,估值与期望值的差值经过动态数据模型计算,得到调节系统抽气设备转速的输入量,进行稳流量进气控制,最后应用于某型号发动机进气部件防冰试验。试验结果表明:发动机进气模拟系统运行稳定可靠,输出的进气流量符合试验要求,进气稳流量控制精度达到0.1 kg/s。
