Abstract

This work deals with the design of Commande Robuste d’Ordre Non Entier (CRONE) control strategy for the speed control of DC motor. The systematic design of three generations of CRONE control strategy is detailed. The transfer function of DC motor is derived analytically and represented as a second order model. Using this model the three generations of CRONE control strategies is designed and tested in simulation. The servo and regulatory responses of all the three generations of CRONE control strategy is compared and the result is reported in terms of error indices. The simulation results show that the third generation CRONE control strategy is more effective and gives superior performance over the other.
