Active control of wind excited structures using fuzzy logic
The first stage in the development of a fuzzy controller for active control of vibration in a wind excited tall structure is reported. The initial rule base of the fuzzy controller is developed based on the input/output data obtained from the performance of the system under a state feedback controller. The performance of the developed controller is validated through computer simulation. The controller is applied to both the building model from which the rule base is extracted and another building with similar dynamics but different parameters. The developed controller has significantly outperformed a state feedback controller and a previously developed intuitive fuzzy controller in terms of the maximum required control force. The amplitude of the steady state oscillation produced by the state feedback controller has, however, proved to be marginally better than the other two controllers.
