Title: Robust Verification of Hybrid Systems
Abstract: Cyber-physical systems (CPSs) consist of complex systems that combine control, computation and communication to achieve sophisticated functionalities as in autonomous driving in driverless cars and automated load balancing in smart grids. The safety criticality of these systems demands strong guarantees about their correct functioning. In this talk, we will present some of our work on formal verification techniques for cyber-physical systems analysis using the framework of hybrid systems. Hybrid systems capture an important feature of CPSs, namely, mixed discrete-continuous behaviors that arise due to the interaction of complex digital control software (discrete elements) with physical systems (continuous elements). We will focus on certain robustness properties of these systems, and present scalable techniques based on abstraction-refinement for their analyses.

Title: Trying to Keep it Real: 25 Years of Trying to Get the Stuff I Learned in Grad School to Work on Mechatronic Systems
Abstract: This talk is about the difficulty of making well known and widely accepted advanced textbook control techniques work in an industrial environment, particularly with mechatronic systems that have large numbers of flexible modes. I will go through the methods that fail if done the standard way and the adjustments I have learned to make over the years which get a lot of them to work. I will also go over the methods that seem to work robustly and without much thought in the industrial environment, explaining why they do work. Finally, I will try to show that understanding the differences and commonalities in these two world views allows us to use the principles of one to improve the other.
