摘要

Hysteresis is a property of systems that do not instantly follow the forces applied to them, but react slowly, or do not return completely to their original state. A velocity based active vibration control, along with a special class of hysteretic models using passive functions are presented in this paper. This hysteretic model is based on a modification of the Bouc-Wen model, where a nonlinear term is replaced by a passive function. The proposed class retains the rate-independence property of the original Bouc-Wen model, and it is able to reproduce several kinds of hysteretic loops that cannot be reproduced with the original Bouc-Wen model. Using this class of hysteretic models, a chattering velocity-based active vibration control scheme is developed to mitigate seismic perturbations on hysteretic base-isolated structures. Our hysteretic model is used because of its simplicity in proving the stability of the closed-loop system; i.e., a controller is designed using the proposed model, and its performance is tested on the original hysteretic system, modeled with Bouc-Wen. Numerical experiments show the robustness and efficiency of the proposed control algorithm.
