Hybrid Controller Design for Two-Floors Structure against Northridge Earthquake

Abstract

In this study, an adaptive neural network based fuzzy logic controller (ANNFLC) and a PI (Proportional and Integral) controller are used together as hybrid controller for deflection control of two degree of freedom building-like structure system against scaled Northridge Earthquake experimentally. Proposed structure consist of two floors with a shake table and a cart which is mounted on the second floor as active mass damping (AMD) and controlled by hybrid controller. Training and testing data of ANNFLC are determined by using behaviour of PI controlled system against Northridge. Thus, ANNFLC is created and it's control performance is combined with PI controller's effect to achieve small deflection responses of the floors. Obtained hybrid controlled results are compared with passive and PI controlled results and presented in the form of graphics.
