Fault tolerance or resiliency aspects of large-scale systems with networked embedded sensors and actuators need to be taken into consideration at design time and not be an after-the-fact addition to an already completed (not necessarily fault-tolerant) design. While there has been some important progress in fault-tolerant distributed control systems, most of the recent work has focused on specific systems and provide answers in particular domains, but offer little insight for other applications. The paper presents such fault-tolerant distributed control system architecture, using robust fractional order controllers. The controller design algorithm is based on a bio-inspired optimization method. The simulation results highlight the advantages of the control system in different fault scenarios.
