Also, an ideal PID controller causes a derivative kick when used in the feedback control system especially for a step change in the set point. Thus, an implemental form of the PID controller that is based on augmenting Eq. (1) with a first order filter of the derivative term is used instead. This can be achieved either by a series or parallel configuration. Most often, the derivative term multiplied by the filter transfer function is used on the measured variable rather than on the controller error

Electronic `noise' can cause sudden changes in the sensor signal input to the controller
resulting in sudden error changes in the controller output. This is especially true in the
derivative part of a P+I+D controller. where this sudden rate of change causes the
derivative action term to change dramatically. A change in set-point can also produce
derivative kick and, to a lesser extent, proportional kick.
