Response Control of a Large Civil Structure equipped with Magnetorheological Dampers Conference Paper uri icon

abstract

  • This paper proposes a systematic design framework for vibration control of seismically excited civil structures employing magnetorheological (MR) dampers. The framework consists of nonlinear system identification and semiactive nonlinear control system: (1) a multi-input, multi-output (MIMO) autoregressive exogenous (ARX) input model-based Takagi-Sugeno (TS) fuzzy identifier is applied to a large building structure equipped with highly nonlinear hysteretic MR dampers subjected to earthquake disturbances (2) Based on the identified building-MR damper system model, a set of Lyapunov-based controllers are designed such that the building-MR damper system is globally asymptotically stable and its performance on transient responses is also satisfied. To demonstrate the performance of the proposed design framework, a twenty-story building structure employing multiple MR dampers is studied. It is shown from the simulation that the proposed control system design framework is effective to mitigate seismically excited responses of a large building-MR damper system. ©2009 IEEE.
