drag acceleration

the technique of feedback linearization is used to track the reference drag acceleration profile.

对参考阻力加速度剖面的跟踪采用反馈线性化方法。

basing on the estimated range-to-go, the reference drag acceleration profile is updated every period.

衍化算法通过对剩余航程的估算，周期性更新参考阻力加速度剖面。

many forces such as the forces of centrifugal, flow drag, fluid acceleration, the fluid attached acceleration and mechanical drag acting on the particles, in which the mechanical drag force is the most complex.

颗粒在分选过程中主要受到离心力、水流阻力、水流加速度作用力、水流附加加速度作用力及颗粒机械阻力等，其中机械阻力最为复杂。

The weight will drag them a bit during the acceleration phase.

重量将在加速阶段期间拖拉他们一点点.
