MPPT for Magnus wind system with DC servo drive for the cylinders and boost converter

This paper presents a MPPT for Magnus effect wind system with a DC servo-drive system (DC drive and brushless DC motor) driving the rotating cylinders of the turbine. The optimal rotation of the cylinders to deliver the maximum power extracted from the wind turbine is tracked by a HCC (Hill Climbing Control) algorithm acting on the servo drive. The proposed wind system consists of a PMSG (Permanent Magnet Synchronous Generator), a three-phase diode rectifier, a DC/DC (boost) converter and a resistive load. The boost converter also uses the HCC algorithm (Hill Climbing Control) to track maximum power operating point. Therefore, the MPPT (Maximum Power Point Tracking) for a magnus wind system requires both tracking for optimal cylinders speed and the optimal generator speed.
