【摘要】 文中在 MATLAB 环境下,运用最小二乘分段多项式拟合的方法对脉冲推力发动机的推力—时间(f-t)关系的实验数据进行了拟合,得出了较为精确的推力—时间关系曲线,为进一眯对超高速动能弹的控制系统进行分析和设计提供了条件。更多还原

【Abstract】 The least square piecewise polynomial fitting method is presented in the paper,and used to fitting the test data of impulsive thruster f-t characteristics in MATLAB,as a result,an accurate f-t curve is found.It makes a premise to the analysis and design of the control system of hyper-velocity kinetic energy missile in the future.更多还原
