Study on fuzzy control algorithm of high-rise buildings structural vibration

Abstract

In view of vibration models of high-rise buildings with podium, on the basis of analyzing its structural equation of motion, it applies the fuzzy control algorithm to control simulation on high-rise buildings models with 12-storey main building and 3-storey podiums, that is using the fuzzy control strategy to control the force output of semi-active control device of MR damper. The fuzzy control as a branch of intelligent controls can well and proficiently bring operators' subjective experience and intuition into the control system, and it analyzes and synthesizes the system from the point of features of the system and the overall optimization. It simulates the displacement of top storey and velocity & time-histories curve, and obtain damped percentage through the comparison of results without control, with evident result.
