3 Challenge Problems with Cyber Physical Systems and IoT

I will present 3 challenge problems where computation and communication are tightly coupled to control large, complex and “messy” plants. These span safety-critical domains of medical devices, energy-efficient buildings, and autonomous vehicles.

1. Medical Devices – From Verified Models to Verified Code
The design of bug-free and safe software is challenging, especially in complex implantable devices that control and actuate organs whose response is not fully understood. Safety recalls of pacemakers and implantable cardioverter defibrillators between 1990-2000 affected over 600,000 devices, 41% of those were due to firmware issues. I will describe our efforts to develop synthetic clinical trials to go from 100's of real patient signals, map them to our heart models, perturb the models to generate 10,000's of heart models across a range of conditions and then feed them for closed-loop evaluation with medical devices. Such computational modeling and simulation of medical medical devices in the closed-loop context of the physiology we are able to provide regulatory-grade evidence and insights prior to conducting an expensive clinical trial.

2. Energy Systems - Data Predictive Control
In the US, energy prices have summer peaks that are over 32X their average prices and winter peaks that are 86X. How can buildings respond to massive swings in energy prices at fast time scales? Demand response (DR) is becoming increasingly important as the volatility on the grid continues to increase. Current DR approaches are completely manual and rule-based or involve deriving first principles based models that are extremely cost and time prohibitive to build. I will describe our recent efforts on the problem of data-driven end-user DR for large buildings that involves predicting the demand response baseline, evaluating fixed rule based DR strategies and synthesizing DR control actions.

3. Autonomous Systems – Plan Verification and Execution
Autonomous vehicles have already driven millions of miles on public roads, but even the simplest scenarios, such as a lane change maneuver, have not been certified for safety. This is a significant problem as the insurance liability of autonomous vehicles currently is entirely on the manufacturer as there is no systematic method to bound and minimize the risk of decisions made by the vehicle’s decision controller. I will describe APEX, a tool for autonomous vehicle plan verification and execution across a variety of driving scenarios.

Rahul Mangharam is an Associate Professor in the Dept. of Electrical & Systems Engineering and Dept. of Computer & Information Science at the University of Pennsylvania. His interests are in cyber-physical systems which involves the tight coupling of communication, computation and control with physical systems. His current focus is on applications within medical devices, energy efficient buildings, automotive systems and industrial wireless control networks.
Rahul received the 2016 US Presidential Early Career Award (PECASE), the 2016 DoE CleanTech Prize (Regional), the 2014 IEEE Benjamin Franklin Key Award, 2013 NSF CAREER Award, 2012 Intel Early Faculty Career Award and was selected by the National Academy of Engineering for the 2012 US Frontiers of Engineering. He was the Stephen J. Angelo Term Chair Assistant Professor at the University of Pennsylvania from 2008-2013. He received his Ph.D. in Electrical & Computer Engineering from Carnegie Mellon University where he also received his MS and BS in 2007, 2002 and 2000 respectively.
