“…The SMC technique is among the nonlinear techniques that have been widely spread in several fields because of its advantages, especially in the case of external factors [46,47]. The negative of this control is the presence of the phenomenon of chattering that determines its uses [45,49]. In addition, the complexity, especially in cases of complex systems, where is difficult to implement.…”

“…In the SMC, there are 2 sections, discontinuous and continuous parts, where the continuous part is related to the system under study [44], which makes it difficult to apply the SMC technique in complex systems such as 7-phase motors. The SMC technique has been used in several different fields such as renewable energies [45][46][47][48][49]. The SMC is characterized by the phenomenon of chattering, which is determined by the use of the SMC technique [50].…”

This work presents a novel direct reactive and active power control (DRAPC) of grid-connected doubly-fed induction generator (DFIG)-based dual-rotor wind power systems. The designed DRAPC technique employs an intelligent modified sliding mode controller (IMSMC) to directly calculate the required rotor control voltage so as to eliminate the power ripples and the instantaneous errors of reactive and active powers without involving any synchronous coordinate transformations. Thus, no extra current control loops are required, thereby simplifying the system design and enhancing the transient performance.The rotor inverter is controlled by traditional pulse width modulation, which eases the designs of the power converter and the AC harmonic filter. Simulation results on a 1.5-MW grid-connected DFIG system are provided and compared with those of the traditional DRAPC with proportional-integral controllers. The designed DRAPC technique provides enhanced transient performance similar to the traditional DRAPC technique and minimizes the current, active power, and torque ripples.
