Abstract

The paper deals with robust gain scheduled controller design applied for active vibration suppression of flexible structures. The experimental set-up is a three-storey flexible structure with an active mass driver placed on the last storey. First, system identification experiments are performed and the plant's uncertainty is deduced. Next, robust controller design with constraint on the control signal is presented. For a better trade-off between control performance and control constraint a gain scheduling approach is investigated. Finally, the control system is tested experimentally, when the input disturbance is a scaled historical earthquake record (1940 El Centre). The experimental results show that the proposed robust gain scheduling control approach offers higher performance levels and can handle effectively extreme control conditions, such as reconnection of the control system after power failure. All results presented in the paper are experimental results.
