Modeling and Control of a Micro Turboshaft Engine

随着航空推进技术的发展,串联混合动力推进系统将会成为未来的发展方向之一。涡轴发动机作为其中重要的动力来源,有必要对其进行仿真建模及控制系统的设计。在此背景下,基于Simulink/T-MATS平台,利用部件级建模原理搭建了一个轴功率为5 kW的微型涡轴发动机动态仿真模型,并在此模型的基础上设计了一个串级PID控制器。仿真结果表明该模型符合设计要求,控制器的控制效果和抗干扰效果较好。

With the development of aviation propulsion technology,series hybrid propulsion system will become one of the future research directions.As one of the most important power sources,turboshaft engine needs simulation modeling and control system design.In this context,based on SIMULINK/T-MATS platform,A dynamic simulation model of a miniature turboshaft engine with a shaft power of 5 kw was built using the principle of component-level modeling,and a cascade PID controller is designed according to this model.The simulation shows that the model meets the design requirements,and the control effect and anti-interference effect of the controller are very well.
