Maximum power point tracker of a wind generator based on the Flatness-based control

This paper presents a novel control law for a Permanent Magnet Synchronous Generator (PMSG) driven by a wind turbine (WT) and connected to a battery bank via an AC/DC converter. A nonlinear control strategy called the “Flatness-based control” (FBC) is proposed. The novel algorithm gives a simple method, based on trajectories planning, that minimizes the copper losses in the PMSG stator, and, in addition, achieves the maximum of power captured by the WT. The controller parameters are easy to tune as their choice relies on a simple the pole placement. The main contribution of the paper is to show that FBC is compatible with any MPPT strategy. The validation of new control strategy is performed by simulation.
