If there are cases in this case, can you give us a few thanks?!

Overshoot, you can first increase the P, the effect is not good, then tune I

A good change quantity meeting improves overshoot, but a steady time grows and slows down. If the time becomes longer, you can adjust the integration to become larger, but also cause frequent shocks, which means that the integration time is too large, but also to minor adjustments.
