PID plus implementation

[ErikHeijdens]

Hello,

For my control algorithm I have to use a PID+ controller. This is due to stability problems when using a normal PID controller.

The high frequency roll off gives the stability I need. A image is included in where the form of the PID+ controller is described.

There are standard VI's for pid controllers. But how can I implement this kind of controller? Can I use a transfer function VI?

For a other measurement I can use a PID controller. The measured data is of waveform type so I get a coerciondot. How can I fix this?

Kind regard,

Erik
