Abstract

In this paper, a variable structure controller is proposed to control the torque of brushless doubly fed induction generator with considering maximum torque per Ampere (MTPA) strategy. Based on this control approach, a sliding mode controller with a PI is designed in order to reduce the torque pulsations during steady-state behavior while the fast response and robustness merits of the classic DTC are preserved. Also this method decreases the copper losses with minimizing the magnitude of power and control windings currents without deteriorating the dynamic performance. The presented method, guarantees maximum power point tracking (MPPT) with a desirable operation. The simulation results verify an accurate, quick and robust operation of the brushless doubly fed induction generator for wind turbine applications.
