The AMB using PID controller have big overshoot, weak disturbance rejection ability and difficult adjustment of parameters, so it is not satisfied.
但是传统的PID控制器用于磁力轴承的控制时，超调大，参数整定困难，抗扰能力差，难以取得满意的控制效果。
When basic flows appear in the form of stationary atmosphere or global easterly, the external forcing in the tropics triggers only a weak disturbance in the vicinity of itself.
当基流为静止大气或全球东风时，热带外强迫力只能在其附近激发很弱的扰动。
Weak as it is, the disturbance in the wind field is discernible.
该风场的扰动虽然很弱，但是还是可以看得出来。
