This paper presents a historical overview of research in reconfigurable flight control with a focus on work done in the United States. For purposes of this paper, the term reconfigurable flight control is used to refer to software algorithms designed specifically to compensate for failures or damage of flight control effectors or lifting surfaces by using the remaining effectors to generate com...

Run-time partial reconfiguration of programmable hardware devices can be applied to enhance many applications in high-end embedded systems, particularly those that employ recent platform FPGAs. Partial Reconfigurable FPGAs allow tasks to be placed and removed dynamically at runtime. These reconfigurable systems have a 2-layer hardware and software architecture that permits a variety of differen...

The In this paper the problem of reconfiguration in hierarchical control of piecewise-affine systems in discrete time is considered as the choice of input constraints applied to the low-level control. It is shown how such reconfiguration can provide fault-tolerance to actuator faults while reducing the computational complexity of low-level control. The approach is based on partitioning the stat...

The Airspace Playbook is a set of airspace configuration scenarios that augment the National Severe Weather Playbook rerouting scenarios. Each rerouting “play” would be accompanied with a candidate dynamic airspace reconfiguration. Typically, this would involve adjustments of sector boundaries in increments of existing sector components. Occasionally, these reconfigurations may combine two or m...

Abstract: This paper presents a general framework for model-based fault detection and accommodation for a class of distributed parameter systems with control actuator faults. A set of dedicated observers, each with its own time-varying threshold is constructed to detect the occurrence of fault in the corresponding actuator and reduce fault detection time. Additionally, an adaptive diagnostic ob...

In this paper, the problem of configuration selection i.e. sensor/actuator placement for piecewise affine (PWA) systems subject to both sensor and actuator faults is considered. A method is proposed that provides a tool for the design phase to decide about the optimal placement of sensor/actuators where the reconfigurability of the system subject to sensor and actuator faults is also taken into...

This paper addresses an extension of the fault accommodation problem for sampleddata systems resulting from quantization of continuous linear systems presented by the authors in a previous in work. Only the output signal has been assumed to be measurable and a control reconfiguration technique is developed in order to cope with stepwise actuator faults and quantization errors. A simulation stud...

Abstract: The intensive deployment of Information Technology in manufacturing systems gives manufacturers an opportunity to promote make-to-order business models and mass customization of products. Facing this wide range of customer needs requires manufacturing control systems to be adaptable to variable demands in terms of product specifications or intrinsic system changes. To this end, the co...

In this paper, experiments are conducted in order to quantitatively evaluate the tradeoffs between design complexity and area overhead, reconfiguration flexibility, and reconfiguration latency of two reconfiguration interfaces, i.e. SelectMAP and JTAG. The results show that the SelectMAP interface is highly suitable when reconfiguration latency needs to be kept to a minimum at the expense of a ...
