Abstract

Strong earthquake ground motions hinder the use of seismic vibration control systems in buildings because they may damage the sensors or cables connected to controllers. To maximize the vibration control of the building even during large earthquakes, we designed a redundant vibration control system that tolerates errors in sensing instruments and the accuracy deterioration in the estimated state variables. To monitor the accuracy of each sensor, we introduced a reliability parameter that quantifies the accuracy of the estimated state variables. Using this, we designed a new algorithm based on linear-quadratic Gaussian control theory to reduce the building seismic response and obtain a redundant and robust building vibration control system.
