Interval max-plus fault-tolerant control under resource conflicts and redundancies: application to the seat assembly

Abstract

This paper reports the development and application of an interval max-plus fault-tolerant control to a seat assembly system. Such systems will undergo a profound change because novel seats for autonomous driving contain expanded safety systems and are more voluminous and heavy. Automated guided vehicles are a promising means of transportation in these systems, but they require dedicated and advanced control systems. This rises new challenges because such an assembly system can dispose both shared resources and redundant elements. This paper presents a fault-tolerant control framework, which allows dealing with systems containing shared resources as well as redundancies. It also overcomes the problem of uncertainties and constraints, which are inevitable in industrial reality.
