Abstract
A modified criterion for designing a linear time-invariant observer is studied. This criterion is a compromise between errors due to stochas tic and modal-type deterministic signals. The advantage of this criter ion is in its design potentiality to take care of both transient and s teady-state behavior. Theoretical properties such as existence, unique ness, and stability of the optimal solution can be guaranteed for dete ctable systems under a weak stabilizability condition, which is satisf ied by any reasonably defined problem. Moreover, under the criterion, relationships with other existing methods are also discussed.
