Building Cyber-Physical Energy Systems

The built environment, as hallmark of modern society, has become one of the key drivers of energy demand. This makes for meaningful application of novel paradigms, such as cyber-physical systems, with large scale impact for both primary energy consumption reduction as well as (micro-) grid stability problems. In a bottom-up approach we analyze the drivers of CPS design, deployment and adoption in smart buildings. This ranges from low-level embedded and real time system challenges, instrumentation and control issues, up to ICT security layers protecting information in a world of ubiquitous connectivity. A modeling and predictive control framework is also discussed with outlook of deployment for HVAC optimization to a new facility for research from our campus.

A Backstepping Control Method for a Nonlinear Process - Two Coupled-Tanks

The aim of this work is to compute a level backstepping control strategy for a coupled tanks system. The coupled tanks plant is a component included in the water treatment system of power plants. The nonlinear-model of the process was designed and implemented in Matlab- Simulink. The advantages of the control method proposed is that it takes into consideration the nonlinearity which can be useful for stabilization and a larger operating point with specified performances. The backstepping control method is computed using the nonlinear model of the system and the performance was validated on the physical plant.
