Mechatronics is a scientific discipline that aims at the integration of mechanics, electronics, computing and control of automatic systems into a single concept. If these systems also possess certain characteristics, such as modeling uncertainties, nonlinearities, hysteresis, delays and the action of external disturbances, then they are called complex systems. The type of system on which we focus our attention will be a complex mechatronic system. Specifically, we consider an experimental wind turbine with a magnetic suspension device. The main objectives of the project can be summarized in the following three points: (1) active control of the base isolating magnetic suspension; (2) detection of failures in the turbine by image digital processing; (3) modeling and control of the system with sensor delays. To achieve these objectives, and for the purpose of experimental simulations, a disturbance generation mechanism is required. To this end, a Stewart platform is currently available, which can produce multidirectional excitations. Moreover, we are also interested in the vibration control of the wind turbine in order to reduce the movement of the tower, improving the system performance. In this case, a novel experimental configuration is the placement of the wind turbine on top of an excitation-actuation system formed by a tandem of two Stewart platforms. The material for the construction of the second platform is requested in the project and the research team will be responsible for its design, assembly and tuning. The experimental validations and testing can be carried out in three different laboratories. The first one is located at the Polytechnic School of Engineering of Manresa (EPSEM) of the UPC; the second one is the laboratory of the CoDALab research group in Barcelona and finally, access to the laboratory of the University of Agder in Grimstad (Norway) is provided by Dr. Karimi, member of the working team and leader of the Mechatronics group of the Norwegian University. We believe that the project fits perfectly on the field "Safe, efficient and clean energy" because it focuses on the study and development of advanced control techniques for improving and optimizing wind turbines. On the other hand, it is also related to the field "Action on climate change and the efficient use of resources and raw materials", since any action tending to produce clean and sustainable energy without resorting to expensive and limited extraction of raw materials will have a positive impact on climate change on Earth and represents an intelligent use of natural resources. Additionally, the project also seeks to consolidate an interdisciplinary and international research team composed by mathematicians and engineers, with the possibility of producing interesting results for the energy and industrial sectors.
