摘要:对全飞行包线内的发动机控制问题展开研究,分析了包线的划分和标称点的确定问题,提出了根据发动机进口参数的相对变化指标对飞行包线进行划分的方法。同时将二自由度H∞鲁棒控制方法引入航空推进系统的控制器设计中,克服了传统鲁棒控制器无法兼顾系统的性能和鲁棒性要求的缺陷。最后在设计的航空发动机数控系统快速原型化实时仿真平台上进行了仿真,证实了所提出的全包线划分方法的正确性和所设计的增益调度鲁棒控制器在某型航空发动机全包线控制上的良好性能。 |

Abstract:Design of full flight envelop aeroengine controllor system is studied,the problems of dividing flight region and the selection of nominal plant in corresponding region are analyzed,and the method of dividing flight region based on the engine inlet parameters is introduced.Then,two degreesoffreedom H∞ loopshaping design procedure is applied to aeroengine control system to improve the tracking performance while maintaining stability robustness.At last,the hardware intheloop simulation based on the realtime simulation platform is carried out,and the results have verified the validity of the flight envelop dividing method and the twodegreeoffreedom robust control system design method for aeroengine full envelop control. |
