    A recently proposed implementation of output feedback based on signal processing eliminates the practical overhead of physical operation in closed-loop. Additionally, the ,virtual implementation facilitates realization of of multiple closed-loop systems from a single test in open loop, allows for complex gains, and removes the constraint of closed-loop stability. Care, however, must be exercised in the design of the closed-loop systems as the errors in these are governed by the intrinsic approximations in the open-loop identification. The present paper offers an examination of this item when the closed-loop systems are designed for parameter estimation in updating numerical models of structural systems. The differences between physical realization and the proposed virtual implementation are discussed, and the pivotal points outlined are demonstrated in the context of the numerical examination with a structural system.
