This paper deals with the modeling and the control of a four wheels mobile robot driven by four independent brushless DC motors. The modeling approach considers the mechanical and the electrical characteristics of the four brushless DC motors and the dynamical model of the studied mobile robot. A control strategy based on IP control and Sliding Mode Control (SMC) is presented. It aims to allow the...
Nowadays, there is a tendency to increase the capacity of wind turbines, multilevel converter is a realistic alternative in such high power applications. As the wind power penetration continues to increase, grid codes have been revised to require wind farms to operate as conventional power plants. This paper proposes a reconfiguration scheme of control strategies for doubly fed induction generator...
Nowadays, there is a tendency to increase the power of wind turbines. Multilevel converter is a realistic alternative in such high power applications. As the most widely used variably speed wind turbine, doubly fed induction generators (DFIG) are very sensitive to grid disturbances. Moreover, grid codes have been revised to require wind turbines to provide Low Voltage Ride-Through (LVRT) ability....
