Data-driven method for the quantitative fault diagnosability analysis of dynamic systems
TL;DR: Data-driven realisations of distinguishability based on both fault-free data and fault data are proposed and a novel efficient method for computing distinguishability via the pseudoinverse is proposed.

Finding a trade-off between observability and economics in the fault detection of chemical processes
TL;DR: It is shown that in closed loop operation, a shorter time for detection may result from retuning the controller at the expense of higher product variability, and an optimization approach is proposed for finding a trade-off between the economic losses resulting from lack of detection and loss resulting from higherproduct variability.

Fault tolerant control based on continuous twisting algorithms of a 3-DoF helicopter prototype
TL;DR: Fault tolerant controllers, based on the Continuous Twisting Algorithm, are designed for robust stabilization of a three-degree-of-freedom helicopter prototype and simulations and real-time experiments confirm that CTA-based controllers counteract additive faults.

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.
