Verification of High-Order Control Barrier Functions by Computing Class K Functions
arXiv:2502.03409
Abstract
High-order control barrier functions (HOCBFs) can enforce system safety, but it must be verified that a system can actually implement a given HOCBF (or collection thereof). We address this need by formulating a sequence of SOS programs that verify HOCBFs by computing class K functions associated with them. We show that if solutions to these SOS programs exist, then a system is guaranteed to remain safe at runtime. Simulations show this approach in practice.
