Abstract
The emerging concept of cyber-physical system (CPS) and its related technologies (e.g., smart power grid, smart city) aim to revolutionize the way we perceive and control the physical world around us.
CPS is a network of collaborating computational elements that control physical entities. It has a broad range of application areas: energy, infrastructure, transportation, communications, military, healthcare, manufacturing, etc.
 
As a result it has been identified as a key area of research worldwide, and many conferences are organized each year to promote research on this promising concept.
Research in CPS is intrinsically inter-disciplinary as it includes computation, communications, control, networking, and signal processing problems. Statistical analysis is a common tool used to handle such problems.
 
In this talk, we focus on sequential (i.e., online) statistical methods for detection, estimation, stochastic control, and cyber security. Sequential methods are designed to satisfy the timing constraints in a typical CPS. We further propose to use a non-uniform sampling technique called level-triggered sampling to achieve resource (e.g., energy, bandwidth, computation) efficiency. We provide theoretical and numerical results to show the efficacy of the proposed methods.
