About

Zhennan Fei is a leading researcher in the field of discrete event systems (DES) and supervisory control theory, with a particular focus on switched and hybrid architectures. His most influential work, "Invariant-Based Supervisory Control of Switched Discrete Event Systems" (2016), has garnered 12 citations and introduced the foundational concept of switched DES (s-DES). In this technical note, Fei systematically explores the representational and computational power of s-DES, demonstrating how this framework can more effectively describe and analyze complex DES behaviors, specify control requirements, and manage event-driven dynamics. His contributions have advanced the theoretical underpinnings of supervisory control, offering new invariant-based methods that enhance the flexibility and robustness of automated systems. Fei’s work is particularly notable for bridging the gap between classical DES theory and the practical demands of modern, reconfigurable manufacturing and cyber-physical systems. By providing a rigorous yet accessible formalism, he has enabled researchers and engineers to design more adaptive and reliable control architectures. His research continues to influence the development of supervisory control strategies for systems that must operate under varying modes or environmental conditions.
