Actuator Failure Identification and Compensation Through Sliding Modes
IEEE Transactions on Control Systems Technology, 2007Co-Authors: M.l. Corradini, G. OrlandoAbstract:The actuator failure compensation problem is addressed in this brief. It is considered an uncertain linear plant, which is supposed to undergo unknown failures causing the plant input Components to be stuck at some uncertain but bounded time functions. A sliding-mode-based control policy is presented, guaranteeing the detection of the fault and the identification of the Failed Component by means of a suitable test input. Once the Failed Component has been identified, the control law is reconfigured, redistributing the control activity among the controllers still working. The proposed controller has been tested by simulation on a benchmark problem

Actuator failures compensation: a sliding mode control approach
2006 14th Mediterranean Conference on Control and Automation, 2006Co-Authors: M.l. Corradini, G. Orlando, G. ParlangeliAbstract:This paper addresses the problem of accommodating actuator failures for an uncertain linear plant. This latter undergoes failures causing the plant input Components to be stuck at some unknown but bounded time varying functions. A sliding mode control policy is presented, guaranteeing fault detection and the identification of the Failed actuator Component by means of a suitable test input. Once the Failed Component has been identified, the control law is reconfigured, redistributing the control activity among the controllers still working.

A new technique for troubleshooting large capacitive energy storage banks
PPPS-2001 Pulsed Power Plasma Science 2001. 28th IEEE International Conference on Plasma Science and 13th IEEE International Pulsed Power Conference. , 2001Co-Authors: E.s. Fulkerson, J. HammonAbstract:Many pulse power systems rely on large numbers of inductively isolated high voltage capacitors configured in parallel for energy storage. Often when an energy storage capacitor fails there is little or no external indication. Identifying the Failed Component can be a time consuming and potentially hazardous operation. We have developed a new noninvasive (i.e. no dismantling of the bank is required) technique that greatly improves personnel safety as well reducing troubleshooting time. We present the theory of operation, a complete description of the battery-powered hardware, test results and techniques of operation.

Multi Topology Routing based IP Fast Re-Route for Software Defined Networks
2016 IEEE Symposium on Computers and Communication (ISCC), 2016Co-Authors: Selcuk Cevher, Mustafa Ulutas, Sedat Altun, Ibrahim HokelekAbstract:The strict Quality of Service requirements of real-time services in communication networks necessitate the fast recovery from link/node failures by activating alternate paths which avoid the Failed Component. Multi Topology Routing (MTR) based IP Fast Re-Route (IPFRR) technologies rely on virtual topologies (VTs) to seamlessly forward the IP packets during network failures. In this paper, we implement a new MTR based IPFRR technique for Software Defined Networks (SDN) which uses the Multiple Routing Configurations method to construct VTs. Our approach leads to self-recovering SDN against failures. Out preliminary results show that our approach considerably reduces the failure recovery time compared to the reactive recovery process in SDN.

Multiple Routing Configurations for Fast Re-route in Software Defined Networks
2016 24th Signal Processing and Communication Application Conference (SIU), 2016Co-Authors: Selcuk Cevher, Mustafa Ulutas, Sedat Altun, Ibrahim HokelekAbstract:Real-time services in IP networks require a fast switching of disrupted traffic to alternate paths in case of link/node failures to satisfy their stringent Quality of Service requirements. Multi Topology Routing (MTR) based IP Fast Re-route (IPFRR) technologies rely on virtual topologies to seamlessly forward the IP packets during network failures by activating the proactively computed alternate routes which avoid the Failed Component. Multiple Routing Configurations (MRC) is a widely studied MTR based IPFRR technique which provide full protection against network failures. In this paper, a new MRC-based fast re-route technique for Software Defined Networks (SDN) is proposed. Our experimental results show that our approach considerably reduces the recovery time from network failures compared to the reactive Shortest Path First (SPF) routing.
