摘要/Abstract

摘要： 针对航空发动机预测控制特点,采取了两项措施:一是根据航空发动机动态响应规律选择预测模型;二是采用双曲线正切函数柔化输入矢量。仿真表明,由于这两项措施的应用,当航空发动机数学模型随飞行条件的变化而变化,预测模型不变,预测模型与航空发动机并不匹配的情况下,仍能保证较好的预测控制性能。

Abstract: Two measures have been taken for predictive control of the aero-engine.One is to select the predictive model according to the dynamic response law of the aero-engine.Another is to intenerate the input vectors by hyperbola tangent function.The simulation results show that the performance of predictive control is good although the aero-engine model varies with the change of condition in flight while the predictive model keeps unchanged.
