A new method for the control reconfiguration of stable Hammerstein systems after actuator faults is described. The class of Hammerstein systems contains input-saturated systems, which are ubiquitous in practice. The new reconfiguration approach uses a virtual actuator that permits to keep the nominal controller in the loop. The concept of virtual actuators is extended to reflect the nonlinear p...

Reconfiguration is concerned with relationships among solutions to a problem instance, where the reconfiguration of one solution to another is a sequence of steps such that each step produces an intermediate feasible solution. The solution space can be represented as a reconfiguration graph, where two vertices representing solutions are adjacent if one can be formed from the other in a single s...

To apply run-time reconfiguration there is need for an appropriate model to understand reconfiguration. System on chip technology allowed the use of complex low gate/price new type of FPGA. Modelling reconfiguration and using Matlab tools is possible to simulate and rapid prototype vector control systems. The paper presents the reconfigurable models as introduced by Luk, Cheung, Shirazi and Ath...

optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

A major asset of modern systems is to dynamically reconfigure themselves to cope with failures or component updates. Nevertheless, designing such systems with off-the-shelf components is hardly feasible: components are blackboxes that can only interact with others on compatible interfaces. Part of the problem is solved through Software Adaptation techniques, which compensate mismatches between ...

Design and analysis of reconfigurable VLSVWSI array architectures is an increasingly complicated task, especially in evaluating the impact of reconfiguration mechanisms on performance, overhead, and yield. In this paper, we present an integrated computer-aided design environment, the VAR (VHDLbased Array Reconfiguration) system, for the tasks of design, diagnosis, reconfiguration, simulation, a...

The fast growing VLSI industry demands new techniques for configuring the FPGA. When it comes to defence and space application the configuration of the FPGA becomes more crucial. When it is required to configure the FPGA automatically, the need arises of more sophisticated and fast techniques for reconfiguration of FPGA. In the space application, the effect of radiation changes the bit patterns...

In this paper, a robust reconfiguration approach based on Mixed Integer Programming (MIP) is proposed to minimize loss in distribution systems. A Depth-First Search (DFS) algorithm to enumerate possible loops provides radiality constraint. This provides a general solution to the radiality constraint for distribution system reconfiguration/expansion problems. Still, imprecision and ambiguity in ...

In this paper, a lightweight autonomous reconfiguration approach is developed for Field Programmable Gate Arrays (FPGAs). Under the Multilayer Runtime Reconfiguration Architecture (MRRA) paradigm, hardware configuration information is read and operated on directly at runtime to provide low overhead dynamic reconfiguration. This enables a standardized set of Application Programming Interfaces (A...

Component & connector architecture description languages (C&C ADLs) provide hierarchical decomposition of system functionality into components and their interaction. Most ADLs fix interaction configurations at design time while some express dynamic reconfiguration of components to adapt to runtime changes. Implementing dynamic reconfiguration in a static C&C ADL by encoding it into component be...
