Abstract This paper proposed a control strategy based on feedback-linearization control theory to design the controller of the direct-driven permanent magnet synchronous generators (D-DPMSG) system. In order to maintain the D-DPMSG system stably operating on the optimal regimes, tracking the wind turbines’ optimal operating characteristic curve quickly, a nonlinear control strategy based on dynamic models of the components of the system is derived. Comparing to the conventional PID control strategy, this new nonlinear controller based on feedback-linearization control theory shows better performance of rotor speed with smaller overshot and faster response when subjecting to stochastic wind. Intensive simulations are shown to demonstrate the effectiveness of the proposed scheme in tracking the maximum power operating curve.

Key words： Permanent magnet synchronous generator PID control feedback-linearization control MPPT
