An Integrated Fuzzy Control System for Structural Vibration

Numerous studies of control systems of civil structures and infrastructure have recently been conducted. To develop structural control systems, it is necessary to consider their special features such as complexity, uncertainty, and size. In order to be able to consider these features, fuzzy theory has been applied to structural control systems. This paper proposes an integrated fuzzy active control system based on fuzzy ensemble learning. The proposed method includes 2 fuzzy active control systems, a fuzzy ensemble system, and a gating network. Two fuzzy active control systems are constructed by applying particle–swarm optimization. The fuzzy ensemble system assigns a performance grade to each fuzzy active control system according to control effects from input patterns. The gating network determines final control force based on the weight of their performance grade. By introducing fuzzy ensemble learning, structural response is reduced more than when response is controlled by individual fuzzy active control systems.
