| Abstract: | By means of the complex optimization method, the characteristic curve of stick force vs. displacement on aircraft steerage stick is drawn up through fragmenting and fitting a good many sampled curves of stick force vs. displacement of aircraft steerage stick by actual test. A least-square formula of fitting to a beeline passing a certain dot is derived. This optimization algorithm has merits of wide selec-ton range of initial value, reliability and rapidly convergence. |
