      With over 20 industrial patents and 200 research papers, Dr. Mario Garcia-Sanz is one of the inventors of the TWT direct-drive variable-speed pitch-controlled multi-megawatt wind turbine, of the TWT variable-speed hydro-wind turbine and of the EAGLE airborne wind energy system, as well as the inventor of optimum planning algorithms for electrical distribution networks and of numerous advanced industrial controllers, among other innovations.

      Dr. Garcia-Sanz was a Full Professor at the Public University of Navarra -UPNA (1995-2009) in Pamplona, Spain, and a Research Scientist and Professor at the CEIT-IK4 research center (1988-1995) and the University of Navarra -TECNUN (1988-1995) in San Sebastian, Spain. He also served as a Visiting Professor at the Control Systems Centre, UMIST (UK, 1995); at Oxford University (UK, 1996); at the Jet Propulsion Laboratory NASA-JPL (California, 2004); at the European Space Agency ESA-ESTEC (The Netherlands, 2008); and at Case Western Reserve University (Ohio, 2009).

      In 2009 Prof. Garcia-Sanz moved to Case Western Reserve University (CWRU), Cleveland, Ohio, as the inaugural Milton and Tamar Maltz Endowed Chair Professor in Energy Innovation. He established the Control and Energy Systems Center, where he is currently the Director (

      Prof. Garcia-Sanz has been the Principal Investigator of over 50 funded research projects for industry, defense and space agencies and research centers. He also works as an expert on wind turbine design and control engineering in patent litigation related matters at the European Courts in the UK and Spain.

      Over the past two decades his laboratory has been globally recognized as one of the most active research groups in the study and application of Quantitative Feedback Theory (QFT) robust control engineering. In particular, Prof. Garcia-Sanz has developed new control theory in the QFT arena for multi-input multi-output (MIMO) plants, for distributed parameter systems (DPS), for time-delay processes, for nonlinear switching control systems, for feedforward controllers, as well as new methods to apply the Nyquist stability criterion in the Nichols chart, to calculate the QFT templates and bounds and to design the robust controllers. In addition, Prof. Garcia-Sanz has applied the new control theory to numerous industrial systems and commercial products, including among others:

- Wind energy systems: The nonlinear and robust control systems for the TWT family, large multi-megawatt variable-speed direct-drive multi-pole wind turbines (1.5, 1.65, 2.5 MW), including pitch control, yaw control, active/reactive power control and voltage control systems for a high grid penetration level.

- Spacecraft systems: The Darwin mission, a formation flying high-precision telescope-type spacecraft with flexible appendages (ESA-ESTEC). The proposed MIMO QFT control solution achieved the best performance among the participants in the European benchmark.

- Environmental systems: The first QFT control system for a municipal waste water treatment plant (Crispijana, Vitoria, 300.000 people), with simultaneous nitrates and ammonia removal.

- Radio telescope systems: The NRAO Green Bank Telescope (GBT) is the largest mobile radio telescope in the world. The proposed control solution dealt with the azimuth and elevation multi-motor systems and improved the telescope's frequency range of operation and precision.

- Manufacturing systems: M.Torres converting machines for the lightest weight and most fragile structured tissue paper with simultaneous control of line speed and paper tension.

- Smart cities: An adaptive robust control system for central heating systems (Giroa, CEIT). The smart building solution improved significantly the energy savings and temperature control and was awarded by the IET (London, UK).

      As a Full Professor of the Public University of Navarra and Senior Advisor for European companies Dr. Garcia-Sanz played a central role in the design and field experimentation of advanced commercial multi-megawatt wind turbines for industry in the last 25 years. Among others, he worked with Gamesa, Acciona, M.Torres, MTOI, IngeTeam, CENER, Eaton Corporation, Enercon and Siemens. Besides, a number of his former PhD students and Master students are currently principal investigators and head of departments of some of the principal wind energy companies and renewable energy labs worldwide.

      In the electrical power systems arena Prof. Garcia-Sanz has also been involved with numerous industrial projects related to modeling, simulation, monitoring and control of the electrical grid. Among other, he developed Advanced fault detection systems for high voltage transmission networks, Active/reactive power and voltage control systems for wind turbines at high grid penetration level, and Optimum planning algorithms for electrical distribution networks for electrical utilities and companies like Iberdrola, REE, Arteche, Team, AEP, First Energy, ABB, EEQ, etc.

       In the spacecraft and aerospace fields Dr. Garcia-Sanz worked with the European Space Agency (ESA/ESTEC), NASA-JPL, US Air Force (AFIT), Sener, Deimos Space and the US National Radio Astronomy Observatory (NRAO-GBT). He has led a number of projects related to nonlinear and QFT robust control design for telescope-type spacecraft with very demanding specifications, for satellites with flexible structures, for formation flying spacecraft projects and for extra-large radio telescopes: Darwin mission, Laser Interferometer Space Antenna (Lisa Pathfinder) mission, High Precision Acquisition and Tracking System (HiPATS) mission, Proba-3 mission, and Advanced control systems for the Green Bank Telescope.

      In addition, for over 15 years Dr. Garcia-Sanz worked as the Senior Advisor for the President of the MTorres Group, leading the projects on Large multi-megawatt variable-speed direct-drive multi-pole wind turbines design and control (1.5, 1.65, 2.5 MW); Dynamic control of wind farms and grid integration; Water desalination systems using renewable energy; Solar energy systems; Offshore wind turbines for extreme weather conditions; Ocean waves energy conversion; Design of a new generation of Hydro-Wind turbines; Offshore and onshore wind farm development; Parallel kinematics and advanced robots for carbon fiber manufacture in aerospace and wind energy industry; Advanced paper converting machines; etc.

      As an entrepreneur Dr. Garcia-Sanz founded CoDyPower LLC, a control, dynamics and power system consulting firm specialized in control systems, wind energy and optimum planning of electrical distribution networks. The company works in the U.S.A., Europe and Latin America. One of the company's latest projects is the optimum design of the electrical distribution network for the Historic Center of Quito (UNESCO World Heritage Site), in Ecuador. The design was made with the optimum planning algorithms developed by Prof. Garcia-Sanz for electrical distribution systems.

      Prof. Garcia-Sanz's three books, "Robust Control Engineering: Practical QFT Solutions", Taylor & Francis (2017), "Wind Energy Systems: Control Engineering Design", Taylor & Francis (2012) and "Quantitative Feedback Theory: Theory and Applications", Taylor & Francis (2006) are best-selling books in the QFT robust control and Wind turbine technology fields. His QFT Control Toolbox for Matlab is considered as the top CAD tool for designing quantitative robust control systems.
