چکیده مقاله:
Optimal control of base-isolated and non-base-isolated buildings subject to earthquake excitation are considered. The control force at any instant is determined on-line through minimizing a quadratic time-dependent performance index based on the total energy imparted to the structure and the control effort. This control algorithm is based upon the use of discrete actuators and sensors that exert the control force and monitor the response of the building. Having constant gain matrices makes this algorithm more efficient and easier to implement. The effect of time delay on the efficiency of the algorithm is investigated . Comparisons have been made to demonstrate the effectiveness of the proposed method
