Fault-tolerant control is an important means to avoid safety-critical situations and shut-downs of machines and processes due to the occurrence of faults or failures. The scientific aim of the project is to elaborate new methods of fault-tolerant control of networked systems such that the function of the overall system is retained by re-distributing the overall control aim among the subsystems after a failure has occurred and a subsystem is no longer able to satisfy its aim. The architecture used does not include a coordinator, but the subsystems have to make their decisions based on local information and information that they have received over a digital network. The components of the new fault-tolerant control architecture should be elaborated in three steps, which concern the design of networked trajectory-following controllers, the decentralised fault diagnosis and the cooperative reconfiguration of the control units. The results will be experimentally evaluated.

容忍故障的控制是避免由于故障或故障的发生而导致的机器和流程的关闭机器和流程的重要手段。该项目的科学目的是详细阐述对网络系统的耐断层控制的新方法，以便通过在发生故障发生后的子系统之间的总体控制目标来保留整体系统的功能，并且子系统不再能够满足其目标。所使用的体系结构不包括协调员，但是子系统必须根据他们通过数字网络收到的本地信息和信息做出决定。新的容忍故障控制体系结构的组成部分应三个步骤详细阐述，这涉及网络轨迹跟随控制器的设计，分散的故障诊断和控制单元的合作重新配置。结果将进行实验评估。
