涡桨发动机一体化建模与控制系统动态仿真

以某型单转子涡桨发动机为研究对象，分别建立发动机、螺旋桨和执行机构的数学模型。在此基础上，研究带有前馈环节的比例-积分-微分（PID）控制器，形成包含发动机、螺旋桨、控制系统和执行机构在内的涡桨发动机一体化数学模型。开发涡桨发动机离线仿真平台，对发动机的动态特性进行图形化仿真。仿真结果验证表明：所建立的涡桨发动机一体化数学模型满足设计要求，反映了各子系统之间的复杂集成和耦合关系，利用系统模型仿真进行控制系统的组合优化能够有效提高系统性能。

Integrated Modeling and Control System Dynamic Simulation of Turboprop Engine

Taking a single-rotor turboprop engine as the research object,the engine,propeller and actuator mathematical models were respectively established.A proportional-integral-differential (PID) controller with a feed-forward section was added to form an integrated turboprop mathematical model including engine,propeller,control system and actuators.A turboprop offline simulation platform is developed to study the dynamic characteristics with graphical simulation.The simulation results verify that the integrated model can meet the design requirements and reflect the complex integration and coupling relationship between subsystems.Combinatorial optimization of control system can effectively improve system performance.
