Neuro-scond Order Sliding Mode Field Oriented Command for DFIG Based Wind Turbine

Abstract

In this paper, we present a comparative study between second order sliding mode control (SOSMC) with two-level pulse width modulation (2L-PWM) and neuro-second order sliding mode control (NSOSMC) with two-level fuzzy space vector modulation (2L-FSVM) of reactive stator power and active stator power control of the doubly fed induction generator (DFIG) for wind energy conversion systems (WECSs). The validity of the proposed controls techniques is verified by simulation tests of the DFIG-based wind turbine systems (WTSs). The total harmonic distortion (THD) of rotor current, reactive stator power, electromagnetic torque and active stator power is determined and compared in the above strategies. The obtained results showed that the proposed NSOSMC control with 2L-NSVM technique have electromagnetic torque, reactive stator power and active power with low ripples and low rotor current harmonic distortion than SOSMC control scheme with conventional PWM technique..
