PIDFeedforward

PIDFeedforward

is an option to PIDTune that controls the reference weights used for the feedforward filter.

Details

  • For a PID controller , the feedforward weights and affect what fraction of the reference signal to feed the proportional and derivative terms of the controller.
  • Possible settings include:
  • None{1,1}; use no weights
    Automaticautomatically compute weights
    b{b,1}; set the proportional weight
    {b,c}set proportional and derivative weights
