In a previous paper [1], the identification algorithm is presented for feedback active controlled systems. However, this method can only be appllied to complete measured systems. The aim of this paper is to present a combination of the identification algorithm and the modal superposition method to control the incomplete measured systems. The system response is expanded by modal eigenfiinction technique. The extemal excitation acting on some first modes is identiffied vvith a time delay and vvith a small error depending on the locations o f the sensors. Then the control forces will be generated to balance the identiffied excitations. A numerical simulation is applied to a building modeled as a cantilever beam subjected to base acceleration.
