A comparison between integer and fractional order algebraic approaches for on-line parameter estimation and position control of DC motor

This paper compares the performance of Integer and Fractional order Algebraic estimator approaches for identifying on-line parameters and states of the motor. Identified parameters would be used to update an adaptive position control scheme. Adaptive position control is implemented using robust sliding mode control and fractional order sliding mode control methods. Effect of external disturbance (noise) on above techniques is also analyzed. Simulation is carried out which shows a superiority of fractional method. Results of both methods are compared and briefly discussed at the end.
