Description
Summary:This paper presents a new control technique to track the maximum power point for variable speed wind turbine with a separately excited integral generator and transformed to the battery through a controlled DC-DC converter. The proposed strategy controls the step speed ratio via the rotor angular speed to an optimum point at which the power coefficient is maximal for a given blade pitch angle. The controller based on the backstepping technique. A formal analysis based on lyapunov stability is developed to describe the control system performances in addition to closed-loop global asymptotic stability; it is proved that the controller actually meets the MPPT requirement. The above results are confirmed by simulations.
