Ideal PD Controller¶

The ideal PD controller is designed for phase-lead compensation. It is used if the transient response is insufficient or if the system is unstable (phase rise of 0 ° to 90 ° ). It is not used if the controlled system itself does not have an integral characteristic.

The ideal PD controller is mostly used for educational purposes. It is difficult to implement in practice, and the D-term amplifies the noise in the control system.
