模型不确定性线性系统的鲁棒故障检测滤波器设计
Design of robust fault detection filter for uncertain linear systems with modelling errors
摘要
Abstract
The problems related to the design of observer-based robust fault detection filter (RFDF) for uncertain linearsystems with both modellling errors and unknown inputs were studied. By introducing a new performance index, the RFDF de-sign problem could be formulated as an H∞-optimization problem, which was solved by suitably selecting RH∞ post-filter andobserver gain matrix such that the generated residual could achieve the best trade-off between the sensitivity to fault and the ro-business to unknown input, modeling errors as well as control input. The design example and its simulation results demonstratethe effectiveness of the proposed approach.关键词
