A System Decomposition for Sensor Location in Fault Detection and Isolation
نویسندگان
چکیده
In this paper we consider linear systems with faults. We present a new system decomposition well suited for sensor location in the Fault Detection and Isolation problem. We deal with this problem when the system under consideration is structured, that is, the entries of the system matrices are either fixed zeros or free parameters. To such structured systems one can associate a graph. We present a structural decomposition of this graph which extends previous results. This decomposition is based on the analysis of particular separators. This finer structural decomposition allows to characterize all the solutions in terms of location of possible additional sensors.Copyright c ©2005 IFAC.

متن کاملAn LPV Approach to Sensor Fault Diagnosis of Robotic Arm
One of the major challenges in robotic arms is to diagnosis sensor fault. To address this challenge, this paper presents an LPV approach. Initially, the dynamics of a two-link manipulator is modelled with a polytopic linear parameter varying structure and then by using a descriptor system approach and a robust design of a suitable unknown input observer by means of pole placement method along w...
