| 中文摘要: |
| 应用复合形法的最优化方法，对实际测试获得的飞机杆力-杆位移采集数据，进行分段直线拟合绘制出杆力-杆位移特性曲线，并推导了过定点的最小二乘直线拟合公式。该方法允许参数初值选择范围宽，并具有算法简单、可靠，收敛速度快的优点。 |
| 英文摘要: |
| 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. |
