航空发动机电驱动滑油泵控制算法研究

Control algorithm for a certain type of aviation engine electrically driven oil pump

采用B.M.捷米道维奇模型,计算了航空发动机典型工况下各润滑点对应的滑油流量以计算的流量作为电驱动滑油泵性能目标值,针对电驱动滑油泵性能控制需求,利用MATLAB软件,通过线性回归求解得到滑油流量与发动机状态关联模型,并以该模型为基础建立了电驱动滑油泵控制算法电驱动滑油泵试验件试验结果表明,该控制算法可行,流量控制精度满足不大于5%的要求。

The corresponding oil flow of each lubricating point under the aero-engine work conditions was calculated using B.M.Tier Mi Doug Vecchi model.With the calculated flow as the performance target val-ue,aiming at control requirements of electrically driven oil pump,using MATLAB software,oil flow and en-gine condition association model was obtained through linear regression method,based on which the control algorithm for electrically driven oil pump was established.The test verified the feasibility of the control algo-rithm,and the flow control accuracy can satisfy the requirement which is not greater than5%.
