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.
