This paper presents a fault reconstruction method for LPV systems which is robust against uncertainty and corrupted measurements. The design is analyzed based on a virtual system resulting from factorizing the input distribution matrix associated with the monitored actuators. The key observer parameter (which is used to define the observer gains) is designed using LMIs to minimize the effect of the...
Finite-frequency H2 analysis is relevant to a number of problems in which a priori information is available on the frequency domain of interest. This paper addresses the problem of analyzing robust finite-frequency H2 performance of systems with structured uncertainties. An upper bound on this measure is provided by exploiting convex optimization tools for robustness analysis and the notion of finite-frequency...
The flexible aircraft model is divided into rigid and flexible models, and the parameters uncertainty model is constructed respectively using linear fractional transformation (LFT). A complete model of the aircraft is obtained by adding its rigid and flexible models at the outputs, then it can be transformed into a single LFT, and the aircraft's dynamics is separated into certainty part and uncertainty...
Recently the adaptive mixing control (AMC) approach has been applied to an airbreathing hypersonic flight vehicle (AHFV) model, and simulation results demonstrate that this adaptive scheme may be capable of improving performance when compared to a non-adaptive mixed-mu design with similar objectives. In this note, the analysis of this AMC scheme's stability and robustness properties is presented,...
