Linear Residual Generators for Fault Detection in Nonlinear Systems
Analysis
This paper presents a systematic method for designing linear residual generators for fault detection and estimation in nonlinear systems. The approach is significant because it provides a structured way to address a critical problem in control systems: identifying and quantifying faults. The use of linear functional observers and disturbance-decoupling properties offers a potentially robust and efficient solution. The chemical reactor case study suggests practical applicability.
