The current biquad IIR filter can represent a derivative part. It's just not exposed in the PID representation.

  • Derive the equations
  • Check whether adding a D part to the math has an impact on dynamic range
  • Expose, implement, map to network interface

@jordens Is this issue still relevant now that the IIRs have been moved to idsp and the dual_iir_configuration.py script exposes derivative control on the filters? I could be missing something here, but this seems stale to me.
