Fault detection algorithm based on a discrete-time observer residual generator - a GPS application

摘要: The aim of this paper is to present a design methodology for an observer-based fault detection filter. This approach allows compute filter gain such that both and disturbance attenuation requirements are accomplished. developments based on H 2 ∞ optimization type methods in the discrete-time framework. existence conditions expressed terms feasibility some matrix inequalities. An important advantage described possibility extend results other classes systems (as sampled-data systems, stochastic with Markovian jumps corrupted multiplicative white noise, etc.) which appropriate Linear Matrix Inequality (LMI) available. In order illustrate derived theoretical results, case study concerning problem Global Positioning System (GPS) integrity monitoring considered.
