速度偏差 jitter
[物] velocity misalignment
- 研究发现,各向异性越强群速度与相速度的偏差越大;
This research illustrates that the stronger is anisotropy the larger is the deviation between group-velocity and phase-velocity. - 同时,在推力角中引入前馈项,用于消除初始位置和速度偏差对软着陆的影响。
Moreover, this paper also added two feedforward items into thrust control angles so as to eliminate the effect produced by the initial position and velocity errors. - 研究汽车车组速度和距离偏差系统的控制问题。
The control problem of car string velocity and distance bias system with overlapping structures is presented.
