基于神经网络的直升机风洞试验自动配平控制系统

Automatic Trimming Control System Based on Neural Network for Helicopter W.T Test

针对原直升机风洞试验配平控制系统的缺点 ,提出将神经网络控制技术引入该配平系统的设想 ,具体设计了神经网络配平控制器 ,在MATLAB6.5NNToolbox上对其进行了训练仿真 ,并编程实现了网络操作模式。试验结果表明 :系统设计是成功的 ,实现了手动与神经网络自动相结合的组合配平控制技术 ,从而提高了配平的自动化。

In view of the main drawbacks of traditional trimming control system of helicopter W.T test,a new control scheme based on neural network is presented.At first the neural network trimming controller is designed in detail, then it is trained and simulated using MATLAB6.5 NN Toolbox.Finally its operating mode is programmed in practice.Experimental results show that the new trimming control system design is successful;it realizes the versatile trimming control technology based on the combination of operator and neural network;therefore it has the characteristics of higher automation and intelligence level,and results in higher data accuracy.
