摘要
研究了E制导方法实现空间飞行器远程交会末制导的问题。在能量最省指标约束下,采用函数极值方法求解出最优交会时间。针对E制导方法对发动机推力可变的要求,采用PWPF调节器对具有常推力轨道发动机的空间飞行器推力加速度进行调制,得到E制导方法要求的"变推力"。仿真结果表明该方法可以实现远程交会末制导且精度较高。
The E guidance method is studied in the terminal phase of long - distance rendezous. Under the constraint of fuel cost function, the optimal rendezvous time is solved by using extremum theory. For the varying thrust requirement of the guidance, the constant thrusts are modulated by the PWPF modulator. The simulation demonstrates the E guidance method can meet the need of the terminal phase with high accuracy.
