摘要

This paper derives a new model for optimal control of smart seismic isolated buildings. When classicaloptimal control is applied to seismic control, a non-homogeneous term will appear in the traditionalRiccati equation, which causes the model unsolvable. Two current optimal control algorithms werederived based on a lot of approximation. In this paper, the control objective function is expressed usingimpulse response of both seismic excitation and the control force, which leads to a new style model ofoptimal control. By defining a dual system according to the resemblance between the companion equationand the state equation, the optimal control force is directly calculated by state transition algorithm. Animproved optimal control algorithm is thus developed, and is named as Sequential Optimal Control(SOC). A 7-story isolated RC frame structure is employed as a numerical example, and simulation resultshows that the proposed SOC not only provide a more reasonable concept for deriving the model, a moreaccurate way of solving the equation, but also numerically improves the control effect of the currentoptimal control algorithms.
