基于MATLAB/Simulink的航空发动机仿真建模
|
摘要
基于MATLAB/Simulink仿真环境对某型航空发动机建立部件级模型,并利用牛顿-拉夫逊法进行求解,得到航空发动机动态模型。在此基础上,利用拟合法建立航空发动机空间状态模型,并对其进行模型精度的验证。验证结果表明:模型精度满足要求,可为航空发动机的性能分析、控制器设计以及故障诊断等研究提供基础支持。
Based on the MATLAB/Simulink simulation environment,a component-level model of a certain type of aeroengine was established,and the dynamic model of the aeroengine was set up by using the Newton-Raphson method.In addition,the fitting method was used to build the aerospace engine space state model,and the accuracy of the model was tested.The results show that the model accuracy can meet the requirements,so it may lay a basis for the performance analysis,controller design and fault diagnosis of aeroengines.
