In this work, a new direct power synergetic-sliding mode (DPSSM) technique based pulse width modulation (PWM) strategy for doubly-fed induction generator (DFIG) integrated to variable speed dual-rotor wind power (DRWP) systems is designed. The designed strategies produce voltage pulse width locations identical to those of a classical two-level inverter. In this novel control a synergetic-sliding mode (SSM) command and PWM technique to replace the hysteresis comparators and the switching table, for generating the reference voltage using PWM strategies for a classical inverter. Compared with traditional direct active and reactive powers control (DARPC), in this novel strategy, the switching frequency is maintained constant, and the undulations of the reactive power, current, torque, and active power are minimized remarkably. Simulation results verify the validity of the designed strategy.
