The field of cyber-physical systems (CPS) is witnessing significant advancements in safety and control, driven by the need for reliable and efficient systems. Recent research has focused on developing innovative methods for safety verification, control synthesis, and uncertainty representation. A key direction is the integration of data-driven approaches with traditional model-based methods to enhance the accuracy and robustness of safety guarantees. Another important trend is the development of novel control frameworks that can ensure safety, smoothness, and performance in complex CPS applications. Notable papers in this area include:
