Summary

The current energy situation is untenable in a long term. A change in the energy sector is required and the wind energy is postulated as a good candidate for this evolution. There are many ways of improving the wind energy, either building bigger struc-tures able to generate large amounts of electricity either investigating new im-provements to make wind energy more profitable. In this project the feasibility of a new kind of wind turbine is studied. This thesis deals with the achievement of getting a proper mathematical model of a new kind of wind turbine, called the inverted pendulum turbine, but also designing a controller able to command this great structure. The inverted pendulum turbine is inherently unstable system. In order to control this wind turbine an optimal control has been investigated: the linear quadratic regulator. This project studies the feasibility of this uncommon wind turbine system design but also promotes sustainable energy and opens a wide range of new possibl
