Modelling and control of a 600 W aerogenerator

A small 600 W aerogenerator operating in isolated mode is considered, under bounded wind and load changes. A model of its wind turbine is proposed, and a control system is designed that operates under low and medium winds. The control system consists of a proportional derivative controller with current compensation, designed for the non-linear averaging model of the boost converter of the aerogenerator, that guarantees stability in the Lyapunov sense and ensures that the current supplied to the load follows a specified current reference. The current reference is generated by a gradient descent maximum power point tracking algorithm.
