Abstract: In this seminar, we will discuss stability-analysis and minimal-recovery problems for perturbed Markov chains, which serve as a fundamental model for autonomous systems operating under stochastic uncertainty and functional perturbations. To tackle the challenges of robustness assurance and resilience quantification, a computational framework is presented that establishes stability criteria through the spatial relation of reachable and invariant sets, introduces a robustness indicator to identify system-critical transitions, and synthesizes minimal recovery strategies to ensure system resilience. The theoretical results are demonstrated through two applications: an ultrasound navigation system that ensures reliable anatomical landmark identification, and a robotic soft tissue surgery plan that guarantees success against anatomical uncertainties.
