Automatic performance control is like having a special helper that makes sure a machine or vehicle works perfectly. Think of it like having a magic fairy that helps you ride a bike without falling off.
The helper, or automatic performance control, is basically a computer system that keeps track of different things like how fast the machine is going, how much power it is using, and how hot the engine is getting. The computer then uses this information to make small changes to how the machine is working so that everything stays just right.
For example, if the machine starts going too fast, the computer might tell it to slow down a little so that it stays safe. Or if the engine starts getting too hot, the computer might tell it to use a little less power so that it doesn't break down.
All of this happens automatically, without any input from you. It's like having a very smart robot friend that knows exactly how to keep your machine working perfectly.
