Abstract

This paper considers the problem of designing minimal-order observer-estimators for both deterministic and stochastic time-varying linear continuous-time systems. Use of an equivalent ‘canonical’ class of observers does much to unify and clarify previous approaches to the problem. The main result is an optimal unbiased observer-estimator which may be implemented off-line with reduced computational effort. Asymptotic behaviour of the deterministic (stochastic) observer-estimator is analysed and related via observability (and controllability) concepts to the structure of the original system. © 1975 Taylor & Francis Group, LLC.
