编辑： Alessandro Bertucci 2018-4-20

Hello,

I'm designing a controller to be deployed and imported as a simulation model in a test rig application using NI Veristand as front end.

The control law code generation for the application is going allright but I'm stuck trying to implement a tunable filter, lowpass Butterworth with capability to change the cutoff frequency and ideally also the order. It's straight forward and I'm able to generate a .dll with constant parameters for the filter but I would like to be able to change the filter bandwidth in run time as I'm able to change the controller gains (they are a constant block in Simulink but Veristand can edit the value since they are imported as parameters).

Thanks for the help
