Abstract :
In this paper, a linear dynamic control is developed for a faulty flexible structure subject to external ground perturbation. This active controller is based on H∞ theory and is designed using linear matrix inequality (LMI) theory. Lyapunov theory is invoked to validate the control design. According to experiments, where a two levels flexible building with active mass damper and external perturbation is employed, show that this strategy improves controller performance when it is compared with a given controller. This design faces the nonlinear structural system too. 20th Mediterranean Conference on Control and Automation (MED12).
