zero plane

The roughness length of vegetation cover surface depends on the type, height, coverage of the vegetation, zero-plane displacement height, free velocity, friction velocity and the atmospheric stratification stability.

植被覆盖面空气动力学粗糙度长度取决于植被类型、植被高度、覆盖度、零平面位移高度、自由风速、摩擦速度以及大气层结稳定度。

Closed-loop system transfer function of inner current loop has the right half plane zero and close from the imaginary axis, so that the control system Q value is larger and the setting time is longer. It lags the system harmonic compensation time.

系统电流内环闭环传递函数中存在右半平面零点且距虚轴较近，这样造成控制系统Q值较大、调节时间加长、系统谐波补偿滞后。
