N2 - Current problems in structural control involve structures with closely spaced natural frequencies (M.J. Balas, 1983). The purpose of this paper is to show how control affects a structure with closely spaced natural frequencies. To develop clear and concrete results, the fundamental case of a structure with only two modes with a single, scalar control input is examined. This demonstrates the effectiveness and limitations of using a single control for two nodes. The following three control algorithms are used: velocity feedback, pole allocation, and optimal control.
