基于NARX非线性辨识技术的航空发动机 嵌入式机载模型计算机实现
The Implementation of Embedded Aircraft Engine on-Board Model Based on NARX Technology
摘要
Abstract
As it is difficult to achieve the onboard model of the aircraft engine for the control system ,we design a kind of identified nonlinear model of NARX(Nonlinear Auto Regressive with Extra Input). And we transplant it in?to the high performance embedded processor system to achieve the engine onboard model. First,a real time NARX model is identified with the test data of some turbofan engine. Then,the NARX model of the turbofan engine is been loaded into the TMS320C6747 control module with the code generation technology. Finally,some interface code has been modified to realized the aircraft engine onboard model and the experiments. The results shows that the identi?fied model has an high accurate precision,and with the DSP platform after loading model the accuracy gets to 92%. Above it satisfies the requirements for the airborne model.关键词
