- 摘要:
- 作为吸气式发动机燃油控制系统的被控对象，燃油调节器的动态特性对调节器自身的性能优化和控制系统设计均至关重要。基于燃油调节器的工作原理，采用集中参数法建立了燃油调节器的非线性模型，对其进行小偏差线性化得到其状态空间模型，计算获得其传递函数，并详细分析了燃油调节器的动态特性影响因素，为燃油调节器性能优化提供参考。通过模型降价简化传递函数模型获得其一阶模型，分析表明一阶模型和原模型的频域特性符合的很好，低阶模型能够表示燃油调节器的动态特性，为燃油控制系统设计和控制参数优化奠定了基础。
- Abstract:
- Fuel regulator is one of the key components of fuel control system in airbreathing engine, and its dynamic characteristics are essential to performance optimization and controller. Based on the working principle of the regulator, the nonlinear dynamic model of the fuel regulator was established with the lumped method. Its state space model was gotten by carrying out small deviation linearization, and the transfer functions were obtained by calculation. The influence factors on the regulator performance were analyzed based on transfer functions, which were beneficial for its performance optimization. Furthermore, the transfer functions was simplified by model reduction. The results reveal that the frequency response of the simplified model are consistent with those of the original model, so the simplified model can express the dynamic characteristics of the regulator. The research is fundamental to dynamic characteristics optimization and controller design.
