PD Control: when deviation occurred, the system will immediately generate some operation load
that is greater than the load generated single handedly by the D action to restrain the increment of
the deviation. If the deviation is small, the effectiveness of the P action will be decreasing as well.
The control objects include occasions with integral component loads, which are controlled by the
P action only, and sometimes, if the integral component is functioning, the whole system will be
vibrating. On such occasions, in order to make the P action's vibration subsiding and the system
stabilizing, the PD control could be utilized. In other words, this control is good for use with
loadings of no brake functions over the processes.
PID Control: Utilize the I action to eliminate the deviation and the D action to restrain the vibration,
thereafter, combine with the P action to construct the PID control. Use of the PID method could
obtain a control process with no deviations, high accuracies and a stable system.
