Control LoopsditRegion3
In a servo loop, the value of an output(such as a motor position) is made to track a control value.
Above: Servo Motor
In
this example, the
acceleration sensor value is compared to the value of the motor position.
If it is greater, the motor turns one way; if smaller, the motor turns
the other way.
But there's a problem- the
responding motor tends to overshoot the control value, causing vibration......
we need to make it less sensitive...
