Design of stable fuzzy-observer-based residual generators for a class of nonlinear systems

摘要

One principle for designing fuzzy-observer-based fault residual generators for one class of continuous-time nonlinear MIMO system is treated in this paper. The problem addressed can be indicated as an approach given sufficient conditions for residual generator design based on fuzzy system state observers. The conditions are outlined in the terms of linear matrix inequalities to possess a stable structure closest to optimal asymptotic properties. Simulation results illustrate the design procedures and demonstrate the performance of the proposed residual generator.
