Having a shared and accurate sense of time is critical to distributed Cyber-Physical Systems (CPS)
and the Internet of Things (IoT). Thanks to decades of research in clock technologies and
synchronization protocols, it is now possible to measure and synchronize time across distributed
systems with unprecedented accuracy. However, applications have not benefited to the same
extent due to limitations of the system services that help manage time, and hardware-OS and

The smart grid is a large-scale, societal-level hybrid cyber-physical system with tight coupling between cyber and physical components. Ensuring availability and reliability of power requires maintaining stability of the power grid even as increasing demand and uncertain renewable power sources push the power system close to its operation limit. In addition, the cyber-enabled grid has multiple entry points, leaving it highly susceptible to cyber attacks by malicious adversaries.

It's common in controller design to assume that the controller reads the sensors and writes to the actuators at the same time instant. This assumption is often violated in practice because the controller executes its code sequentially on a microprocessor. If the microprocessor is "fast enough," often the controller will still work. However, if the sensing and control are done by two different devices that must communicate across a network, the resulting timing uncertainty due to network delays and clock offsets will often destabilize the controller.

Large scale applications of cyber physical systems (CPS) such as commercial buildings with Building Automation System (BAS)-based demand response (DR) can play a key role in alleviating demand peaks and associated grid stress, increased electricity unit cost, and carbon emissions. However, benefits of BAS alone are often limited because their demand peak reduction cannot be maintained long enough without unduly affecting occupant comfort. This project seeks to develop control algorithms to closely integrate battery storage-based DR with existing BAS capabilities.

This poster presents the Pulsar platform, which can achieve better than 5 nanosecond clock synchronization in an indoor environment combining wireless ultra-wideband communication with a chip-scale atomic clock. We discuss the various challenges in synchronization at nanosecond scales then propose and evaluate a proof-of-concept protocol for the same.

This project aims to create a Holonic Multiagent System (HMAS) architecture to support transactive energy market of "active consumers" engaged in buying and selling electricity (locally generated from resources such as rooftop solar photovoltaic) in response to real time electricity pricing. The architecture should require little change to the existing investment in power distribution systems while allowing for the dynamic, adaptive control required to integrate active consumers with current and future combinations of high-variability distributed power sources, such as PV generators a
