Study on Improved Fuzzy Semi-Active Control for the Cable-stayed with MR Damper by Finite Element Simulation

Abstract

An improved fuzzy semi-active control method forparametric vibration of the cable-stayed with MR damper was proposed. The parametervibration control of the cable M22 and the cable M13 of the Hongshuihecable-stayed Bridge was studied. The results show that the effect of theimproved fuzzy semi-active control strategy was better than that of the fuzzysemi-active control strategy. In addition, the proposed fuzzy semi-activecontrol strategy does not need to debug the scaling factor of input variablesand output variables and the MR damper required lower voltages. Therefore，theproposed method makes the fuzzy control more intelligent.
