Time Delay Systems

Control problems due to unknown delay are ubiquitous in engineering. In particular, several problems that occur in power-train systems in automobiles, combustion systems in propulsion and power generation, and ground vehicles that rely on communications have significantly large and uncertain delays. A unique methodology termed Adaptive Posicast Control, has been developed in our research group that has shown enormous improvement in gas turbine systems which include large time-delays and have stringent performance specifications of safety and emissions. Application of this methodology to different problem areas where time-delay plays a major role is currently being investigated. Adaptive control of systems with unknown time-delay using novel strategies is being explored as well.
