A geometric approach to the synthesis of failure detection filters. (English) Zbl 0599.93017
The paper presents a geometric formulation of the Beard-Jones failure detection filter problem for continuous linear constant systems, using the concepts of (C,A)-invariant and unobservability subspaces.
Necessary and sufficient conditions for the existence of a detection filter with arbitrarily assignable spectrum are derived. Practical design procedures are suggested when the failure events satisfy some rather mild restrictions.
Finally, a dual relationship between a generalization of Beard’s detection filter problem and the restricted control decoupling problem is revealed.
