Fault Detection and Isolation for State Affine Systems

摘要

The problem of residual generation for fault detection and isolation (FDI) instate affine systems is studied. Sufficient conditions for the existence of a solution are Presented, and the connection with the geometric theory Of FDI for linear systems is emphasised. Kalman-like Time-varying observers are used for the synthesis of the Residual generators. The theoretical results are illu- Strated by simulation so of diagnosis systems for a Chemical reactors and a distillation column.
