Dr. Zhiqiang Gao received his Ph.D. in Electrical Engineering from the University of Notre Dame in 1990 and has taught at Cleveland State University even since. Faced with ever widening chasm between control theory and practice, Dr. Gao returned to the roots of controls by collaborating extensively with engineers at NASA and industry in solving real world problems, from which the foundation and authenticity of research were rebuilt. A chance meeting and brief discussion with Prof. Jingqing Han in 1995 led Dr. Gao to switch research direction to active disturbance rejection control, and to nurture it from its early, conceptual stage to a maturing and emerging industrial control technology today. In doing so, he made an obscure idea clear and a complex controller easily implementable and tuned in any industrial machinery. Adopting the philosophy of experimental science in research and a humanistic touch in teaching, Dr. Gao and his team bring creative solutions to the real world and vitality of thinking to the young minds.
