Several fractional PID tuning methodologies are investigated and compared. The simulations demonstrate the good performance of the proposed fractional algorithm.engTemperature controlControl systemsHeat enginesDesign engineeringFractional calculusTransfer functionsconference object10.1109/ISDA.2007.157
