A review of the diagnosability of control systems with applications to spacecraft
TL;DR: The definition and influencing factors of the diagnosability of spacecraft control systems are presented to refine existing concepts, and a universal evaluation index system is proposed to further enhance the applicability ofdiagnosability evaluation and diagnosable-based design to spacecraft.
Proceedings ArticleDOI
A model-based approach to fault diagnosis in unmanned underwater vehicles
TL;DR: In this paper, a bank of estimators is used for each actuator's fault type, including the no-fault case, and the estimators are extended Kalman filters due to the presence of nonlinearities in the dynamic models.

Experimental Calibration and Validation of a Simulation Model for Fault Detection of HVAC Systems and Application to a Case Study
TL;DR: The simulated performance of the HVAC unit has been investigated while serving a typical Italian building office with and without the occurrence of typical faults with the main aim of assessing the impact of the faults on thermo-hygrometric comfort conditions as well as electric energy consumption.

Paper: A survey of design methods for failure detection in dynamic systems
TL;DR: This paper surveys a number of methods for the detection of abrupt changes in stochastic dynamical systems, focusing on the class of linear systems, but the basic concepts carry over to other classes of systems.

Parameter estimation for continuous-time models-A survey
TL;DR: The paper reviews the progress of research on parameter estimation for continuous-time models of dynamic systems over the period 1958-1980 and includes a classification system which conforms as closely as possible to that which has arisen naturally over the past two decades.
