Fuzzy control algorithm of civil engineering structure vibration based on cluster analysis

Abstract

With the rise of buildings, how to reduce the vibration of buildings has become a research topic. Structural vibration control in civil engineering is a new subject which studies the theories, methods and measures of structural control. After analyzing the current situation of structural control field based on cluster analysis method, this paper uses fuzzy control strategy to control the force output of semi-active control device MR damper. As a branch of intelligent control, fuzzy control can well bring the subjective experience and intuition of skilled operators into the control system. It analyzes and synthesizes the system from the perspective of system function and overall optimization. After using the basic fuzzy controller to control the structural model, the original fuzzy controller is modified, that is, the three key factors are automatically adjusted to form a self-adjusting factor fuzzy controller.
