Fault-Tolerant Robust Supervisor for Timed Discrete Event Systems: A Case Study on Spot Welding Processes

摘要

In this paper we develop a robust control the- ory to achieve fault-tolerant behaviors of timed discrete event systems (DESs) with model uncertainty represented as a set of some possible models. To demonstrate the effectiveness of the proposed theory, we provide a case study of a resistance spot welding process.
