Abstract

An electro-mechanical position servo is introduced as a benchmark for mode-based Fault Detection and Identification (FDI). The purpose is to provide a simple, industrial system as a platform for comparison of model-based FDI methods, and for the gathering of design experience. Despite a simple system structure, FDI design is intricate when realistic obstacles are included: measurement noise. FDI performance specifications are provided. They include requirements for detection probability and time to detect. Two mathematical models are given: a simple model for use during design, and a complex, nonlinear one for simulation and verification.
