摘要: 为解决协同吸气式发动机高速引起的高温问题,设计了针对换热器的控制算法研究,在设计控制算法研究的过程中,考虑到发动机的强非线性、不确定性以及强耦合性,对于换热器的多输入多输出线性模型进行解耦研究,仿真得到2种不同的解耦方法对于强耦合换热器的解耦效果,得到模糊解耦PID控制器调节时间短、超调量小、具有更好的解耦效果的结论。

Abstract: In order to solve the high temperature problem caused by the high speed of the synergistic aspirating engine, this paper designs a control algorithm for the heat exchanger. In the process of designing the control algorithm, considering the strong nonlinearity, uncertainty and strong coupling of the engine, The decoupling study of the multi-input and multi-output linear model of the heat exchanger is carried out. The decoupling effect of two different decoupling methods on the strongly coupled heat exchanger is obtained. The fuzzy decoupling PID controller has short adjustment time and overshoot. Small, conclusions with better decoupling effects.

Key words: aeroengine, heat exchanger, modeling, decoupling, control
