讲座简介：Cyber-Physical Systems (CPS) must be dependable due to their safety-critical nature. In the meantime, the recent trend to collect a large amount of data from various sensing and communication capabilities has enabled modern embedded software to be more adaptive. Examples include connected and autonomous vehicles, UAVs, and warehouse robots. There are grand challenges to design and operate such systems due to their seemly conflicting requirements: adaptivity needs adequate response to various, often unknown and unpredictable, internal and external situations, while dependability must ensure predictable correctness.
In this talk I present a collection of technical solutions. One is runtime resource management for time-critical CPS software, that dynamically adjust scheduling and software parameters according to system dynamics while guaranteeing real-time reliability (e.g., all timing requirements are predictably satisfied). The other is runtime safety enforcement for CPS through the use of safety guards, which are reactive components synthesized automatically from safety specifications to protect against catastrophic failures. The approach is particularly suitable for adaptive systems that continuously evolve with new data.
