Fault prognosis of discrete event systems (DES) is an active field of research and has become important due to the high demand on systems’ safety and reliability. The aim of this paper is to provide the state-of-the-art on fault prognosis of DES, a

Fault-tolerant controllers keep system operation safe and mitigate the effects of a system malfunction, while the notion of safe fault-tolerant control is also concerned with not driving the system into an unsafe post-fault situation. In this paper,

The search for making industrial systems smarter is a chalenge present in the Industry 4.0 scope. In this new industrial era, the automation processes operate in a more flexible and adaptable way, even if there is a system fault. However, depending o

Supervisory Control Theory (SCT) provides a formal framework for controlling discrete event systems. It has recently been used to generate correct-by-construction controllers for swarm robotics systems. Current SCT frameworks are limited, as they sup

The aim of this paper is to report a new concept of safe controllability using prognosis to deal with problems of fault tolerant control in the framework of discrete event systems modeled as automata. To achieve this goal, a necessary and sufficient

This paper presents a methodology for modeling and controlling autonomous mobile robots and illustrates this approach using a sumo robot problem. The free behavior of the robot and its control specifications are modeled by finite state machines, and
