TLDR
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.Abstract:
A number of methods for detecting abrupt changes (such as failures) in stochastic dynamical systems are surveyed. The class of linear systems is concentrated on but the basic concepts, if not the detailed analyses, carry over to other classes of systems. The methods surveyed range from the design of specific failure-sensitive filters, to the use of statistical tests on filter innovations, to the development of jump process formulations. Tradeoffs in complexity versus performance are discussed.read more

H ∞ -control for Markovian jumping linear systems with parametric uncertainty
Peng Shi,E. K. Boukas +1 more
TL;DR: In this article, the authors studied the problem of H∞-control for linear systems with Markovian jumping parameters and parameter uncertainties, where the jumping rates were assumed to be real, time-varying, norm-bounded, appearing in the state matrix.
