This lecture focuses on the verification of hybrid systems using deductive (theorem proving) methods. We describe hybrid systems that combine continuous and discrete states. We then describe two methods for deductive verification. First, we discuss a computational procedure for constructing Lyapunov-type functions (e.g., barrier certificates) that witness the fact that a hybrid system satisfies certain temporal specifications. Second, we consider control protocols for cooperation and decision making in multi-agent systems, as illustrated by the RoboFlag example introduced in the first lecture. We show how to implement a simple protocol for distributed target assignment in a simplified version of the problem (the "RoboFlag drill") and prove stability of the protocol.

Lecture Materials

Some of the slides are from a short course (Quantitative Local Analysis of Nonlinear Systems Using Sum-of-Squares Decompositions) by Balas, Packard, Seiler, and Topcu.
