TL;DR: In this article, a review of model-based fault diagnosis techniques is provided, starting from basic principles, the properties and limitations of different methods are discussed, and the problems encountered in both the residual generation and evaluation stages of fault diagnosis have been outlined.
Abstract: This paper provides a review of model-based fault diagnosis techniques. Starting from basic principles, the properties and limitations of different methods are discussed. The main aim is to give some guide-lines for the use of model-based methods. Accordingly, the problems encountered in both the residual generation and evaluation stages of fault diagnosis have been outlined. A comparison of quantitative and qualitative methods is also given. Finally, the limitation of model-based methods and the alternative and supplementary use of heuristic knowledge are discussed.

TL;DR: A number of tests carried out on small-size three-phase asynchronous motors highlight the excellent promptness in detecting faults, low false alarm rate, and very good diagnostic performance.
Abstract: A DSP-based measurement system dedicated to the vibration analysis on rotating machines was designed and realized. Vibration signals are on-line acquired and processed to obtain a continuous monitoring of the machine status. In case of a fault, the system is capable of isolating the fault with a high reliability. The paper describes in detail the approach followed to built up fault and non-fault models together with the chosen hardware and software solutions. A number of tests carried out on small-size three-phase asynchronous motors highlight the excellent promptness in detecting faults, low false alarm rate, and very good diagnostic performance.

TL;DR: In this paper, the state of the art of residual generation techniques adopted in instrument fault detection and isolation is presented, both traditional and innovative methods are described evidencing their advantages and their limits and the improvement of analytical redundancy technique performances for better dealing with high-dynamic systems and/or with on-line applications are pointed out as the most interesting needs on which to focus the research efforts.
