The servo system is controlled by using a real-time digital control system based on MATLAB/Simulink tools. Experimental responses are presented and analyzed, showing the effectiveness of the proposed fractional-order algorithms. Comparison with classical PID controllers is also investigated.engFractional PID controllerServo systemFractional calculusFractional controlZiegler-Nichols rulesReal-time controlMATLABSimulinkServomechanismconference object
