Robust Control Engineering (PDF)

Prof. Mario García-Sanz is one of the pioneers in the QFT robust control arena. Over the last 30 years, he has developed new QFT control theory for multi-input multi-output plants, distributed parameter systems, time-delay processes, nonlinear switching and feedforward control, including also methods to apply the Nyquist stability criterion in the Nichols chart, and to calculate QFT templates and bounds. In addition, he has designed many commercial control solutions for industry and space agencies. Customers include NASA-JPL, ESA-ESTEC, US-AFIT, NRAO-GBT, GMRT, Gamesa, Acciona, MTorres, IngeTeam, CENER, Eaton Corporation, Enercon, Siemens, Iberdrola, REE, Sener, EEQ, etc.

With over 20 industrial patents and 200 research papers, Dr. García-Sanz is one of the inventors of the TWT direct-drive variable-speed pitch-control multi-megawatt wind turbine, of the EAGLE airborne wind energy system, of the TWT variable-speed hydro-wind turbine, of the DeltaGrids optimal planning algorithms for electrical distribution networks, and of numerous advanced industrial controllers. In addition, he has been the Principal Investigator of over 50 funded research projects for industry, and worked as an international expert on wind turbine design and control in patent litigation at the British Court in London. As a Full Professor at the Public University of Navarra (Spain) and Senior Advisor for European wind energy companies, he played a central role in the design and field experimentation of multi-megawatt wind turbines for industry, including the advice of many PhD students and engineers in the field.
