Embodiment 1
[0052] The structure of the multi-scale optimal control system for high-precision hypersonic vehicle trajectory optimization is as follows: figure 1 As shown, when the hypersonic vehicle arrives in the airspace of the re-entry segment, the altitude sensor, speed sensor, flight path inclination sensor, horizontal flight range sensor and MCU of the hypersonic vehicle are all turned on. The information collection module immediately collects the initial altitude, speed, flight path inclination and horizontal range of the aircraft when it enters the re-entry segment, and sets the current initial time t 0 = 0s, the altitude sent by the altitude sensor to the MCU is h 0 =80 000m, the speed sent by the speed sensor to the MCU is v 0 =6400m / s, the inclination angle of the flight path transmitted to the MCU by the flight path inclination sensor is γ 0 =-0.052rad, the horizontal range of the horizontal flight distance sensor sent to the MCU is r 0 =0m; final value time t f The condit...
