Model reduction method based on optimization shaping for aero - engine controller 高超聲速機的固定階魯棒控制器的設計
The engine controller is in fact a multi - dimensional , complicated non - linear mapping device of the inputs and outputs . therefore with the ability of mapping non - linear and complex functions , the multi - layer forward neural network can be used to establish these relationships based on the experimental data 發(fā)動機控制器實際上就是一個多維的、復雜的傳感器輸入與控制量輸出的非線性映射裝置,因此,可以利用多層前向網(wǎng)絡所具有的映射復雜非線性函數(shù)的性能,在大量數(shù)據(jù)的基礎上建立起該映射關系。
The hardware designing include the interface with engine controller , such as d / a conversion . we chose the ad75089 which was produced by ad corp . this is a parallel port digital to analog conversion , and i give the presentation about its structure and connection scheme . in order to resolve the contradiction between faster computation and slower display , a buffer storage also needed 第二部分詳細陳述了高速數(shù)據(jù)傳輸卡的軟、硬件設計過程,硬件設計包括dsp與pci總線的接口、 dsp與外部控制器的接口、以及電路卡上的擴展數(shù)據(jù)緩沖區(qū)的設計,并使用專門的工具軟件protel繪出全部硬件電路的設計原理圖。
