The paper presents an energy-to-peak controller design approach for vibration attenuation of seismic-excited building structures with input delay. The time delay for the input is assumed to be uncertain time-invariant but has a known constant bound. An energy-to-peak state feedback memoryless controller is designed to attenuate the system response due to disturbance on the controlled output to a prescribed level even when the input delay exists. The design approach is formulated in terms of the feasibility of certain delay-dependent matrix inequalities. The performance of the presented control approach and the system stability when using this approach are demonstrated by numerical simulation results. It is confirmed by the simulations that the presented approach is a viable and realistic control strategy for applications to seismic-excited building structures.
