The PD controller is a fast controller and can even correct control loops with double integration.
As a result, the PD controller can respond to an impending control error and thus achieve a derivative action during the control process.
In the case of a stabilised controller, deviations between setpoint and actual values can arise as a result of disturbance variables z or a change in the reference variable w, i.e. in the setpoint value.
