Abstract

Processing signals from open-loop system realizations can replace real-time operation using actuators in the design of closed-loop eigenstructures. One merit of the signal processing-based implementation is that it, in principle, allows virtual compensators of user-defined model order since the closed-loop systems are not to be realized during physical testing. The present paper explores the implication of the compensator order in the context of parameter estimation for model updating and provides heuristic recommendations on how to select this order. A numerical example with a structural system of engineering interest is presented that demonstrates the basic points outlined in the paper.
