Abstract:
In the present paper, the improved sliding mode control algorithm are presented. This strategy is based on the combination of sliding mode control and Bang-Bang control theory. The sliding mode control theory in some case does not have appropriate effect in the system, based on this reason, the bang-bang control theory is used as an optimizing theory. The bang-bang control can switch abruptly between the on and off situation, this property can improve the performance of sliding mode control strategy. Also, three thresholds are utilized to decrease the time of using the control system and optimizing the responses of structure. For finding the best responses of structure under the seismic excitation, the actuator of active control strategy is located on different floors. The results of proposed method showed that the best performance of control strategy under the selected seismic excitation gained by locating the control system on the first floor and by adjusting the 3-cm limit.
