constant external interferences. However, if the I action is excessively powerful, it will delay the
responding toward the swift variation. The P action could be used solely on the loading system
that possesses the integral components.
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.
