PID algorith
DON1 had the right idea but to restate: Error = Input - Setpoint (or Setpoint - Input) ErrorTotal = ErrorTotal + Error (once per integral timeframe) ErrorNew = Error - LastError (once per derivative timeframe) LastError = Error (once per derivative timeframe) P = Error * Pgain I = ErrorTotal...- McAden
