Derivative control is used in process control systems where lag time (the time it takes to measure a change) is large. Derivative control is considered difficult to implement and adjust; therefore, it is used only when the amount of lag time is extensive. It is typically used in combination with proportional plus integral control (referred to as PID control) for temperature control and other slow applications. PID controllers may be difficult to adjust.
Derivative control is rarely used with proportional control only. Proportional plus derivative control, referred to as PD control, is desirable in processes where there are several different lag times.
