Performance of a five-storey benchmark model using an active tuned mass damper and a fuzzy controller

This paper focusses on the performance of a five-storey benchmark model using an active tuned mass damper (ATMD), where the control action is achieved by a Fuzzy logic controller (FLC) under earthquake excitations. The advantage of the Fuzzy controller is its inherent robustness and ability to handle any non-linear behaviour of the structure. The simulation analysis of the five-Storey benchmark building for the uncontrolled building, the building with tuned mass damper (TMD), and the building with ATMD with Fuzzy and linear quadratic regulator (LQR) controllers is reported, and comparison between Fuzzy and LQR controllers is made. In addition, the simulation analysis of the benchmark building with different values of frequency ratio, beta (beta = dominant earthquake frequency/fundamental building frequency) using a Fuzzy controller is conducted and the effect of mass ratio, mu (mu = mass of the TMD/total mass of the model) on the five-storey benchmark model using the Fuzzy controller is studied.
