Professor Wei Lin, Named 2017 IEEE Fellow

EECS Professor Wei Lin has been named an IEEE Fellow and is being recognized for contributions to nonlinear control systems.

The IEEE Grade of Fellow is conferred by the IEEE Board of Directors upon a person with an outstanding record of accomplishments in any of the IEEE fields of interest. The total number selected in any one year cannot exceed one-tenth of one- percent of the total voting membership. IEEE Fellow is the highest grade of membership and is recognized by the technical community as a prestigious honor and an important career achievement.

Professor Lin’s pioneering work lies in the development of a non-smooth feedback framework for the control of physical systems such as renewable energy, power systems and smart grid, which are inherently nonlinear and cannot be controlled, even locally, by any linear or smooth feedback. Although tremendous advances have been made during 80’s towards smooth feedback via the differential geometric method, research of non-smooth feedback control was initiated in the 80s but quickly received worldwide attention. However, progress was largely stalled in the early 90s.

Since 1998, Lin and his students have made a series of breakthroughs by developing innovative methods for the control of genuinely nonlinear systems, and then proceeded from it to a wide range of important yet challenging problems such as homogeneous observer design, global and semi-global output feedback control of non-uniformly observable systems, output tracking, finite-time control, and adaptive regulation of nonlinearly parameterized systems by state and/or output feedback. Lin’s work has not only complemented nonlinear control theory but also opened new directions for a large amount of subsequent researches over the years, and significantly advanced the state-of-the-art of non-smooth control theory.
