FUZZY CONTROL OF STRUCTURAL VIBRATION - AN ACTIVE MASS SYSTEM DRIVEN BY A FUZZY CONTROLLER

The authors are engaged in a long-term research project studying the p otential of fuzzy control strategies for active structural control in civil engineering applications. The advantage of this approach is its inherent robustness and its ability to handle the non-linear behaviour of the structure. Moreover, the computations for driving the controll er are quite simple and can easily be implemented into a fuzzy chip. I n this paper attention is focused on the response of a three-storey fr ame, subjected to earthquake excitation, controlled by an active mass driver located on the top floor. The design and the implementation of the controller driving the AMD system are discussed. (C) 1998 John Wil ey & Sons, Ltd.
