Observing a subset of the states of linear systems Indexing terms: Linear networks, Modelling, Dynamic systems
 

Summary: Observing a subset of the states of linear systems
M. Aldeen
H. Trinh
Indexing terms: Linear networks, Modelling, Dynamic systems
Abstract: A selective state observer capable of
asymptotically tracking any arbitrarily chosen
subset of the state vector of linear time-invariant
multivariable dynamic systems is introduced. The
dynamics of the observer are derived from a
model of the subset to be estimated. It is shown
that the only condition for the asymptotic track-
ing of the subset is that the derived model be
observable. A simple and systematic observer
design method is presented and numerical exam-
ples are given to illustrate the properties of the
new observer and its design method.
