A variation of Proportional Integral Derivative (PID) control is to use only the proportional and integral terms as PI control. This reduces the effect of a disturbance, and shortens the time it takes for the level to return to its set point. The methods can be used experimentally on physical systems, but also on simulated systems. As in the case of the PD controller, adding the D-component has the effect that, if laid out correctly, the controlled variable reaches its setpoint sooner and its steady state faster.
