Verriest received the Best Presentation Award in the session ThB25 Communication Delay in Network Control at the American Control Conference, held July 7 in Boston, Massachusetts. Verriest is a professor in the Georgia Tech School of Electrical and Computer Engineering (ECE).\u003C\/p\u003E\u003Cp\u003EVerriest coauthored this presentation entitled \u201cReachability of a Cascade of Linear Systems with Communication Delays\u0022 with the late Uwe Helmke of the Institute of Mathematics at the Julius Maximilian University of W\u00fcrzburg in W\u00fcrzburg, Germany and Paul Fuhrmann of the Department of Mathematics at Ben Gurion University of the Negev in Beer Sheva, Israel. The research is in the area of mathematical systems theory and was conducted while Verriest was on professional development leave in\u0026nbsp;W\u00fcrzburg\u0026nbsp;last fall.\u003C\/p\u003E\u003Cp\u003EVerriest and his colleagues derived necessary and sufficient conditions for a notion of \u0022restricted reachability,\u201d when only the states of certain subsystems in a cascade of systems need to be controllable. This is a more general formulation of a motivating problem when a string of robots communicate from one to the next, while the first in the chain receives the control signals. In this case, the states of the communication systems between the robots are of no concern, but the robots\u0027 states are. Similarly, the states of a river need to be controlled at certain geographic locations such as population centers, while not as much control is needed in the levels of intermediate floodplains. These conditions, cast in a polynomial systems theoretic framework, generalize the Necessary and Sufficient Condition for full reachability of a cascade, derived by Helmke and Fuhrmann in 2015.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EECE Professor\u0026nbsp;Erik I.
