Due to complicated continuous helicopter models and a wide range of constraints, numerical solutions on a mainframe computer have to take a long time. for a given set of initial helicopter states and flight parameters, optimal solutions are fitted by a fourier series. the coefficients of the fourier approximations are then interpolated as functions built by three - layer bp network with inputs of initial flight states and parameters
最後,由於直升機數學模型的復雜性,這給實時優化計算帶來很大困難,本文研究了地面計算機計算的最優軌跡如何在機載計算機上實時顯示,對飛行員的操縱提供參考,即把不同初始條件得到的最優軌跡曲線進行傅立葉部分級數化,得到傅立葉系數,選取合適初始條件作為變量,對這些最優軌跡曲線進行擬和,建立bp神經網路預測模型。
