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控制器处不在，从汽车的巡航控制，调整旋翼速度以保持平稳飞行的机，甚至更奇特的机器，比如这个能在球上保持平衡来移的机器。

PID is greater than or equal to the probability that he misses

PID大于或等于他错过D-1的概率。

At the same time, traditional control methods such as PID control can be combined to achieve stable control and precise navigation of drones.

同时可以结合PID控制等传统控制方法， 机的稳定控制和精准导航。

That’s a bit of a mouthful, so people call them PID controllers.

那句话有点长，所以们称之为PID控制器。

PID, that's the probability that I hit if I throw today, is bigger, we'll make it bigger than equals, let's not worry about the equals for now, it doesn't really matter, so we'll make it bigger than equals just for today.

PID，即我今天投掷时命中的概率，更大，我们将其设为大于等于，暂时不必考虑等于的情况，那并不重要， 所以今天我们只讨论大于等于的情况。

PID controllers calculate three values from this data.

PID控制器从这些数据中计算三个值。
