Multivariate detection of transient regions in a process control system
TL;DR: In this article, a first representation of the operation of the process, or coker heater, is generated based on a first set of the collected on-line process data generated from a set of process variables.

A Re-Examination of Fault Detectability and Isolability in Linear Dynamic Systems
Jie Chen,Ron J. Patton +1 more
TL;DR: In this article, the authors re-examined the fault detectability and isolability of the residual signal of an inverted pendulum system with possible sensor, actuator and component faults.

Detection of Additive and Multiplicative Faults - Parity Space vs. Parameter Estimation
Thomas Höfling,Thomas Pfeufer +1 more
TL;DR: In this article, the parity space approach with adaptive thresholds and the parameter estimation is used to detect and identify additive or multiplicative faults in a d.c.motor, and a combination of both methods is proposed to achieve optimal fault detection.

Multiplicative fault reconstruction using sliding mode observers
Chee Pin Tan,Christopher Edwards +1 more
TL;DR: In this paper, a method for reconstructing multiplicative faults using a sliding mode observer is presented. But this method is based on previous work on reconstructing additive faults, and it is not suitable for the case of nonlinear systems.

Adaptive fault diagnosis and fault-tolerant control of MIMO nonlinear uncertain systems
TL;DR: An integrated fault diagnosis and fault-tolerant control (FTC) methodology for a class of nonlinear multi-input–multi-output systems and it is shown that the system signals always remain bounded and the output tracking error converges to a neighbourhood of the origin of the state space.

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.

Analytical redundancy and the design of robust failure detection systems
E. Chow,Alan S. Willsky +1 more
TL;DR: In this article, a robust failure detection and identification (FDI) process is viewed as consisting of two stages: residual generation and decision making, and it is argued that a robust FDI system can be achieved by designing a robust residual generation process.
A survey of design methods for failure detection in dynamic systems
TL;DR: A number of methods for detecting abrupt changes (such as failures) in stochastic dynamical systems are surveyed in this paper, where tradeoffs in complexity versus performance are discussed, ranging from the design of specific failure-sensitive filters, to the use of statistical tests on filter innovations, and the development of jump process formulations.
