Designing Method of Residual Generator for Multi-sensor Fault Detection and Isolation
摘要
Abstract
In order to solve the problem of multi-sensor fault detection and isolation,a unified fault model for lock-in-place,gain time-varying and bias time-varying is established. We resort the output equation to converted sensor fault into state disturbance of the dynamic system. A residual generator which can well be used to fault detection and isolation is designed. In addition, we also put forward the method of solving unknown parameters in it. The effectiveress of this method is verified through example simulation.关键词
