CEMOS AUTOMATIC oversees the configurations of numerous components, such as concave clearance, drum speed, concave bar, concave flap, fan speed, upper and lower sieve openings, rotor speed, and rotor flap.

CEMOS AUTOMATIC 监控众多组件的配置，例如凹面间隙、滚筒速度、凹面条、凹面挡板、风扇速度、上部和下部筛孔、转子速度和转子挡板。

PID controllers are everywhere, from the cruise control in your car, to drones that automatically adjust their rotor speeds to maintain level flight, as well as more exotic robots, like this one that balances on a ball to move around.

PID 控制器无处不在，从汽车的巡航控制，到自动调整旋翼速度以保持水平飞行的无人机，以及更奇特的机器人，比如这个靠球平衡移动的机器人。
