摘要
针对传统的裕度评估标准难以直观地体现飞机端干扰量对发动机的控制耦合性问题,在飞发一体化架构下开展了航空发动机控制裕度及相应的评估准则研究.基于一种可以在有限频域内采用几何图解法进行控制性能改进的控制理论"几何设计法",本文提出一种新的发动机控制裕度定义方法及评估准则,包括构造满足需求控制裕度的控制器求解方法、评估对比不同控制器的控制裕度和评估固定结构控制器的控制裕度.以某型宽速域组合动力(TBCC)航空发动机作为研究对象,在亚声速巡航典型工况下,基于几何设计理论所设计的控制器,控制性能可以达到控制裕度理论极限的99.61%.部件级模型仿真结果表明,相比于传统比例积分(PI)控制器,基于几何设计理论所设计的控制器的推力控制裕度和综合控制裕度分别提升了7.3%和5.9%,验证了所定义的控制裕度及其评估准则在解决飞发一体控制耦合性问题的有效性.
Abstract
In response to the difficulty of traditional margin evaluation standards to intuitively reflect the coupling problem of aircraft disturbance on aeroengine control,research on aeroengine control margin and corresponding evaluation criteria is carried out under the framework of integrated flight-propulsion architecture.A novel method for defining aeroengine control margin and evaluation criteria is proposed based on a control theory called geometric design method that can improve control performance using geometric methods in a finite frequency domain.This includes constructing a controller solution method that meets the required control margin,evaluating and comparing control margins of different controllers,and evaluating control margins of fixed structure controllers.Taking a certain type of turbine-based combined cycle(TBCC)engine as the research object,under the typical subsonic cruise condition,the controller designed based on geometric design method can achieve 99.61%of the control margin theoretical limit.The simulation results based on the TBCC component level model show that compared to the traditional proportional integral(PI)controller,the thrust control margin and comprehensive control margin of the controller designed based on geometric design method have increased by 7.3%and 5.9%,respectively,verifying the effectiveness of the defined control margin and its evaluation criteria in solving the coupling problem of integrated flight-propulsion control.
