Bumpless transfer demo

The video shows the special connection of PID controller in order the reject rapid changes in manipulated variable (mv) when the controller mode (MAN/AUT) is switched - called often bumpless transfer or bumpless control. The tracking controller input tv is used. When the PIDU controller is switched between MAN and AUT mode, both inputs sp (setpoint) and hv (hand value) have the same value. The UP and DN button can be used for smooth change of setpoint. The lab core is based on REX Control systems available at http://www.REXControls.com
