Experiments in robust control on a laboratory model of a six story building

Reports a series of experiments performed to quantify the potential benefits of using robust control design methodology in active control of building structures. The experimental facility is described, and the design approaches which include H₂ design, μ-synthesis and mixed H₂/μ design are outlined. Experimental results show the ability of the robust control systems to tolerate uncertainty due to high frequency unmodeled modes and due to uncertainty in the natural frequency of the modeled modes
