Active Control of 3-D Irregular Building by Using Energy Based Neuro-Controller
In this paper, a methodology of active control of structures based on modal energy is extended to control the response of irregular structures. The nonlinearities of material and geometry are taken into account in the training algorithm. A three-dimensional (3-D) multi-story irregular building is employed to scrutinize the performance of the improved control strategy. The torsional and lateral responses of the structure and the dynamic behavior of actuators have been incorporated in the control model simultaneously. Thus, the lateral-torsional coupling as well as the structure-actuator interaction is considered. The incident angle of ground motion and the time delay of actuators are also included in the model. El-Centro 1940 earthquake is used to train the algorithm, and then five different earthquake records have been used to evaluate the trained control system. The results of controlled structural responses in each case proved that the proposed control algorithm may be promising in vibration control of 3-D irregular structures.
