Instantaneous Optimal Control of Seismically-Excited Structures Using a Maximum Principle:

An optimal control scheme is proposed for linear dynamic system models, and the optimal control forces are derived using a maximum principle. Numerical examples are presented demonstrating the characteristics of the control scheme. An instantaneous extension to the optimal control method is proposed to deal with the unknown nature of seismic disturbances. Examples of the effectiveness of the method and a tradeoff curve are presented.
