摘要
以某型单转子涡喷发动机为研究对象,在提取该型发动机状态空间模型的基础上,提出了单转子涡喷发动机状态空间模型的稳态及动态的修正算法,获得基于稳态及动态的修正模型。以阶跃输入响应对模型进行了检验,检验结果表明使用该方法修正的状态空间模型具有与原非线性数学模型完全一致的稳态及动态过程响应,解决了单转子涡喷发动机状态空间模型检验与修正的问题。
On the distillation of single rotor turbine engine, a kind of steady and state modification method was provided in single rotor turbine engine state space model, and a model was obtained bases on steady and unsteady modification. The modification model is verified based on its step response. The result demonstrates that this method can achieve a desirable steady state output and an almost exact dynamical behavior as the original nonlinear model, and the modification model solves the test and modification problem in single rotor turbine engine state space model.
