PIDDerivativeFilter

PIDDerivativeFilter

is an option to PIDTune that controls the filtering used for derivative terms.

Details

  • The derivative filter replaces the direct derivative with its filtered version , effectively series connecting a lowpass filter with the derivative.
  • The derivative filter is a first-order system with a pole at . A large value means a fast filter and less filtering effect.
  • Possible settings include:
  • None, no filtering
    nexplicitly specified filter
