Active response-control systems that use fuzzy optimal logic
- International Inst. of Seismology and Earthquake Engineering, Tsukuba, Ibaraki (Japan)
In building structures, it is generally difficult to construct this control system since there are many unknown variables such as the type of structure, material, and construction, and the deterioration of the structural performance with passage of time. In case of controlling the vibration of a structure subjected to earthquakes, it is critical that the response of the control system be quick enough as to minimize time between sensing external turbulence and putting actuators in operation. In this paper the author briefly discusses the classification and characteristics of structural response-control systems, mainly involving active control and hybrid control, control theory, required performance, current trends in structural response-control buildings, the outline of shaking table tests for an active response-control system that uses fuzzy optimal logic and their results, and the prospect for smart-material systems.
