This paper deals with fault detection and classification as a part of our on-going research in the integrated design of reconfigurable control systems. The objective of reconfigurable control is to provide fault-tolerant control in an uncertain or changing environment. This will be accomplished by detecting changes in the current operation of the system from what is expected and then changing t...

A strategy for decomposing a class of constrained linear control allocation problems is considered. The actuators are partitioned into groups of mutually non-interacting actuators. The problem is then divided into a set of sub-problems and a master problem, whose solution approximates the solution to the original problem. For some classes of allocation problems the method is extended such that ...

The paper proposes a control system with the brake and the steering for developing a driver assistance system. The purpose is to design a cruise control method to track the road geometry with a predefined velocity and guarantee the road stability of the vehicle simultaneously. An actuator selection method is developed in the control design, in which the actuator limits, energy requirements and ...

High performance systems, like the F-16, when pushed to their limits encounter qualitative changes in control system properties like loss of controllability or observability. This work identifies and characterizes bifurcations occurring in a nonlinear six degree of freedom F-16 in two scenarios straight and level flight and in a coordinated turn. Phenomena such as stall, tumbling and spin-roll ...

Recent advances in software technology have the potential to revolutionize control system design. This paper describes a new software infrastructure for complex control systems, which exploits new and emerging software technologies. It presents an open control platform (OCP) for complex systems, including those that must be reconfigured or customized in real-time for extreme-performance applica...

Hyperreconfigurable architectures can change their reconfiguration capabilities dynamically at run-time. For reconfiguration they use two types of reconfiguration steps: i) in hyperreconfiguration steps they change their ability for reconfiguration, ii) in ordinary reconfiguration steps they reconfigure the actual contexts of a computation within the limits that have been set by the preceding h...

This report surveys recent results and approaches from the field of control reconfiguration within a general fault-tolerant control framework. Open problems for future research are identified. Control reconfiguration is embedded within a wider fault-tolerant control context and set apart from other approaches to achieve fault tolerance. It is explained why simpler approaches than control reconf...

Nowadays on-line reconfiguration for computer networks is pursued as an alternative approach to keep performance levels when a mal function is presented in the system. In this case, reconfiguration is proposed in three stages. Firstly , computer network presents a degradation in time communication due to the appearance of certain local faults. Secondly, based upon this scenario a strategy for o...
