Abstract

Large number of active vibration control systems existing in the literature has brought lot of confusion for engineers and junior researchers. This study deals with the comparison of different active control systems of a 20-storey building under seismic excitation for three control devices: Active Mass Damper (AMD), Active Bracing System (ABS) and Connected Building Control (CBC). Two different control configurations are considered to add active damping to the building. The first one employs force actuator and displacement sensor and is examined with first and second order Positive Position Feedback, Lead compensators and Direct Velocity Feedback.
The second configuration employs a displacement actuator collocated with a force sensor and an Integral Force Feedback control law.
A total number of 15 control cases are compared from the point of view of stability, robustness, performance and control effort.
